You're #1 priority is survival. Everything else is irrelevant when you don't have food to eat.

If your implication is that bullies turn into cold-blooded killers, I think it is a bit of a wild assumption.

Traders aren't the most professional bunch around. But rumours are generally just that. They don't often have anything substantial to back the up.

A fit, but still untrained, human is more dangerous, relative to other animals, than we tend to think

I think the keyword is not nice, but kind. To be kind is an admirable trait that we should all aspire to be. Niceness is bogged down in its negative associations.
