I also stated that most species do not "kill" their own for food and have a pack mentality, this also goes for humans.
You sure about that? Then how do we account for pecking order in a pack mentality? Do they call all call it quits before someone gets seriously injured? Hell, some of them don't even do it for food. Male lion's kill the helpless young of the pride when they defeat the pride leader, and that's not even for food but just a matter of genetics. There are also slavemaker ants and dolphins can actually take sex slaves (and they murder too, btw).
Oh, I didn't say religion doesn't kill people, however religion "preaches" not to, unless it's for an OK reason.
It seems the bible disagrees with you. Either that or you've got to change the way you think to coincide with the bible. Killing homosexuals has to be "okay" with you, otherwise you're being hypocritical. This extends past the bible and pops up in quite a few holy texts.
People will do many things to survive, murder is just one of those things.
This is true, though, but you need to extend that beyond people. Also religion has no say in the matter, it just serves its purpose in proving that murder will happen (in the name of religion, for example). Relative ethics and morals aside, murder is just a natural aspect of nature and survival. We can decrease its occurrence and we can punish those who commit such acts based on whatever we want to believe (and I emphasize believe), but it's ultimately an act that happens because it will happen because it's unavoidable.
Sounds evil...
