Long, thinky post incoming.
I think humans tend towards being mostly "good" (and by good, I mean tending towards altruism. empathy and being reasonably honest) within their own communities or within circles of people to whom they are fairly close and to whom they relate. Another potentially "good" trait is curiosity, which drives us to seek out novelty and to try and understand the how and why of things (and animals and other people). People seem to develop these qualities as a part of normal development.
What follows is totally my opinion, as I'm no sociologist.
I think people who live in complex, modern societies strongly prioritize their attachments. We really have to in a world where we typically encounter hundreds (at least) of strangers each day, not to mention read about people who "aren't like us" in the media, and (in recent years) navigate through an online world with people who may not always feel real and where we never truly know how common certain attitudes and views are (does a flood of racist posts mean there are tons of racists out there, or is it just a few racist trolls multi posting).
Empathy falls off in that sort of setting, as and there's a tendency to retract and only associate with people with whom one mostly agrees. In a world where people feel like they are outnumbered, and where they're constantly bombarded with new information that opposes what they've always been taught or distracts them from the things they have to do to get by, lack of empathy, not to mention incuriosity, can start to feel like virtues. We start to otherize and to justify callous, even abusive, behavior towards "outsiders."
There are true pathologies that lead to cruel, sadistic, selfish or "evil" behavior in some (I think it's a minority) of individuals, of course--people who
can't form caring attachments, even within their inner circle, or who are gratified by the infliction of pain on the unwilling. But I think a lot of people's everyday cruel, selfish, callous acts and attitudes stem from the fact that we're not really "wired up" to empathize with people or entities we don't know personally, and that we're programmed to prioritize our own wants and needs, and those of our inner circles, over those of people further from us. It's also common to assume one's own experiences are universal and a tendency towards confirmation bias.
I wonder if this might be the reason why society is becoming collectively more selfish and un-empathetic than it once was, with more and more people unwilling to pay for things like health care, education, infrastructure, environmental regulations and so on. When inconveniences or sacrifices are seen (rightly or wrongly) to be helping people we don't know or relate to, we start to act like a bunch of starving dogs in that proverbial "dog eat dog" world and to jealously guard our precious institutions from "outsiders," however we define them. It's particularly bad during periods of belt tightening, whether they be due to a true economic crisis or due to the system being manipulated by those on top so it always
feels like resources are scarce.
It's a huge challenge facing democracy in an increasingly diverse and (supposedly) inclusive and interconnected world.
I don't think other species are inherently more virtuous than we are, though. By their nature, they're more likely to live in worlds where they interact mostly with those from the same population. As far as we know, wolves, crows, and chimps have no mass media or ability to communicate with members of their species that are far away from their current location, or to perceive the ways the behavior of populations on the other side of a continent might affect them.
Social species are often very territorial,
violently excluding rival groups from their territories in behaviors that seem like rudimentary forms of warfare, and some other animals can engage in behaviors that seem to be very cruel to individuals within their own populations who don't quite fit in for some reason.
The issue is that humans, existing in the billions and wielding a greater influence on the planet as a whole than other species do, are in a position that allows our the limitations in our natural capacity for empathy to do unprecedented harm to members of our own, and to members of other species. We're effectively a global population, but we're not equipped to deal empathetically with so many who seem so
different from us.
So, to conclude a very long point, I don't think "uplifted" wolves, crows, parrots, dolphins, chimps, pigs, lions, mongooses, elephants etc. would act just like humans (or like each other). Their social systems and biology would remain fundamentally different, as would their sensory capabilities and the resources they need to survive. But uplifted species with high social intelligence might develop something analogous to our systems of economics and warfare, and there would likely be individuals within their societies who victimize or take advantage of others.
Of course, if they were forced to live within the human centered world we have already created, they'd have to adapt to that too, and they might have to adopt behaviors more like ours to do so.
This is all just speculation on my part, not based on more than my general understanding of social behavior.
