Without going into details, my understanding of deviance is that it is not significantly influenced by genetics. Since all rules/norms/laws are socially created, little or nothing would favour criminal or non-criminal genes. Genes are value-neutral (and of course, evolution has no direction or end purpose).

As Chad pointed out, twin studies are useful in cases like these. We did discuss them in this context in one of my classes and as I recall there was no significance in the data, but I could be wrong, and of course, with probably only a handful of twin studies having been done on deviance ever, there's no solid answer yet.

Behaviour is the combination of environment and genetics. In some cases, genetics have a greater role, in some cases, a lesser one.

Cptn, I can't find where I said I knew of some animal who exhibited "greedy" behaviour, although I well may have. I am more interested in showing that no trait is strictly and distinctly human. I've argued that human greed always has a function (impressing members of the opposite sex, for instance), and under this definition, I would also argue that hoarding, etc. is "greed." Again though, I have no source for this, but I'll post as soon as I find anything out.

For what it's worth, in my mind, altruism falls into the same category as greed. On the surface, neither appears adaptive, but if you look deeper, both are, so in other words, there is no pure altruism (this idea is widely accepted), and there is no pure greed.
