Why would you kill your twin sister?

Too rid the world of the evil that is her sister.

She ate my oreos.

I have to disagree-- 'evil for the sake of it' belongs in saturday morning cartoons. It creates two-dimensional, boring characters.

Give the character a good reason for doing it, not just 'because she was evil.'

If she set out to kill them both, than you've already established that she was suicidal as well as homicidal. So the question is not why she wanted her sister dead, but why she wanted herself dead. There are plenty of cases where suicidal people try to take others with them-- especially family members.

To keep the "evil twin" from harming someone else.

Because she was afraid she too was turning into an evil person because of her sister's influence.

Because the "evil twin" had done something (given her a drug, etc.) that temporarily turned her into someone else.

Because she just learned some surprising revelations that was such a shock that she didn't really know what she was doing.

Want more?

Well, maybe the 'good twin' saw her sister as being more (in that same sense as her), pushing her towards a Cain and Abel type of twist. Maybe you could read the book of Genesis and build on a little of that history; where good is defined in varying levels. (Good to the 10th power is still good but not when compared to the 100th power).

They aren't really twins. They are clones and the 'good' twin is the clone.

Her sister was prettier.

Because the "evil twin" is really William Shatner.

;-)

Even if there were such thing as an "evil" person, i don't think her twin would kill her to save the world from her. She probably wouldn't even be able to see her sister as "evil," even if there was a lot of evidence.

Most teenagers are more interested in self-image, than saving the world. What if twin B had a habit of exposing twin A's faults?

One day, twin A does something seriously embarassing (something harmless but terrifying, like sneezing so hard she wets her pants in public). Fortunately she manages to hide it from her friends . But then twin B shows up and notices. And she jokes about calling Billy and telling him how hilarious it is. And in the heat of the moment, twin A notices twin B didn't fasten her seatbelt, so she drives off the road, not really planning further ahead than that.

Hmmm...yeah, I think that's why I've had a hard time with it. If she murdered someone, how can she get into heaven?

It could be an accident.

Or she could just be mentally unstable and not realize it--e.g., she has multiple personality disorder or severe bipolarism or something?

Maybe the good twin isnt' really the good twin after all. They switched places, there was an incident with a pineapple, and things just got out of hand.

The good twin was never really good - just a good actress.

If they're inseparable, then she had to kill her to keep them together.

Good, bad, she's the one driving

I don't know why she would kill her sister but if the one of them IS evil wouldn't she not be in heaven?

William Shatner... nice.

Just to clarify, the "bad twin' really isn't bad. She's just always been not as good as her sister. And since the bad one is the one that ends up in Heaven, she can't be all that evil.

See why I'm stuck?

She killed herself b/c of depression. She killed her sister b/c the two were so close, Good twin decided bad twin couldn't live without her. either that or i'd go with the oreos theory. Or you ate my eggo.

She killed the sister because she had an incurable, degenerative and painful condition and she couldn't bear the thought of her twin sister living in endless suffering - which also gives you a great dilemma - how does someone who has murdered and committed suicide (because she couldn't live with the guilt and/or didn't want to live without her sister) end up in heaven? Unless the Big Guy takes a plea bargain...

You could even end up with the murdered twin agreeing to go to HELL with the murderer because she can't be without her sister...

Temporary insanity. She was posessed so it really wasn't her doing it.

Have you read TWINS by Caroline B. Cooney?

I'm currently in the middle of it, as I also have a twin story I'm working on (though no one dies).
Anyway, it also has one twin being good and one being evil and someone dying as a result.

I like this one.

Maybe they're not twins at all... Maybe one is a baby stolen by the mother when she lost a twin the first time around. Brings in 'nature vs nurture' issues and also the fact that not many twins are truly identical. Also makes the mother appear rather warped.

As an identical twin myself ...

... my feeling is that you should consider the degenerative/awful disease scenario. That is, the murder/suicide is meant to avoid the awful fate of a slow and agonizing death from X.

I say this because my twin sister and I are always comparing health notes -- on the assumption that if one of us is diagnosed with something (e.g. migraines, recently), the other one is going to end up with it as well.

Well, just my four cents worth (2 for me, 2 for my twin sister)...

Twins have that knack of knowing what the other is thinking, right?

Both see a bomb or a grenade in a school, subway, stadium--wherever and BOTH dive on it simultaneously. She only "killed her sister" by not covering the bomb up enough to shield her sister.

There was a case in the UK a few years ago about twins who started arson attacks, and ended up being sent to Broadmoor (high security mental hospital/prison). These girls were so close that they had their own private language, and rarely spoke to other people, even in their own family. Sometimes at school they copied each others movements in a wierd, robotic way - and sometimes they tried to kill each other (by drowning, on one occasion).
So it could be that they are so close that they can't live with each other, and they can't live without each other.
