I'm in agreement with Lausten and DjVortex -- the person you're talking to has misconceptions about what evolution should have produced, because they seemingly don't have any idea of what evolution is or does. The very idea that "dangerous traits should have left the human race long ago" represents a fundamental misunderstanding of the concept of evolution. It really does sound like they think evolution is a conscious guide, leading life toward some moral or physical ideal -- like the "god" of biology, or something.
There is no "should" in evolution. There's only what is. Humans didn't appear because we were meant to, and we didn't adapt as social or moral creatures because evolution intentionally "pushed" us in that direction. It just so happened that certain traits we had (intelligence, dexterity, social tendencies, etc.) turned out to be beneficial enough that it aided in ensuring reproduction could occur successfully -- and that each next generation would survive successfully enough that it could reproduce, in turn.
Heck, we may not even be the wisest, or most moral species that could have resulted. Maybe things could have happened differently, millions of years ago, and populations could have adapted in some alternative way that would have resulted in beings far more intelligent, responsible, rational, or powerful than we are now. The fact that we humans exist today doesn't make us the "apex" of any honorable endeavor.
The idea that "evil" exists today shouldn't be surprising. As long as certain "evil" tendencies don't result in widespread inability to raise offspring to mating age, those tendencies won't necessarily ever disappear.
"Evil" is as much a problem for biology as it is a problem for physics, chemistry, or geology.
And... frankly, someone who thinks that we could ever get to a point where evil becomes eliminated from society, probably hasn't thought much about the concept of "evil."
