Nothing Personal

This whole world is all about competition.

Even our very existence is borne of competition. (Survival of the fittest, Evolutionary theory, etc)
In the face of competition, how can there be goodness? If resources are scarce; and always remains scarce, how would one expect others to share, give, donate? Similarly, why would one help, assist, facilitate at the expense of themselves? Without moltives, seeking benefits to oneself, selfishness, how can there be kindness, friendliness, selflessness? If doing so defeats the purpose of competition, what other purpose would it serve if not to maintain something as crucial as 'survival'. How can there be any good in this world then? Even if we try and squeeze some pure goodness out, the essence of being human is still hard to be proven as good. Following evolutionary theory, all the good guys have already died. 

Even more complicated is the relationship between these 'good' and 'evil' traits. If they are opposites, aren't they all connected? So is good borne of evil? Or do we only compare good in the face of evil? This in itself holds so much to argue about; quite distinct from the initial paragraph.
