Humans, Viruses and Hell

A dialog from Matrix:
Agent Smith : I'd like to share a...revelation I had, during my time here.It came to me when I tried to...classify your species. I realized that you're not ACTUALLY mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but... you humans DO NOT. You move to an area... AND you MULTIPLY... until every natural resource is CONSUMED. The only way you can survive is to.. spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Humans beings are a DISEASE, a CANCER of this planet...

If there is God, and if he created humans, I really wonder what he had in his mind while creating humans.
1: Killing the same species
2: Killing other species for fun
3: Not fitting anywhere in the food chain

These things lead me to a thought.. Hinduism believes that when you commit N number of good deeds in past/present life, u get to be a human.. For me, thats like a punishment for others.. its like saying if u commits sins, then in ur next life, u'll be surrounded by humans.. That means we are going to be like hell for others :) Is it why we worship God? Coz its natural human tendancy to look for something that we dont have.. or finding grass on the other side always greener. So since we already are in hell, or since we are hell.. we want something better :)

You will say I am thinking/saying is crap... but my point is, all of us on some different planet will make "this" world better :)

I am not exactly an antisocial/antihuman person, but I do feel that we use our so called intelligence in a very very incorrect/inappropriate way. Please dont flood the responses with "u do the same things.. why blame others" etc.. coz I am a human and bound to make mistakes :)
