Not directly jumping into the topic of "does god exist?"
I have to point out that "good" and "evil" are completely based on perception.
There are some things so common that we do them on an almost daily basis. These things may be seen as completely sacrilegious and "evil to another person, and vise versa.
Personally I don't believe in the idea of something or an action being completely "good" or completely "evil".
They're all actions with their own motivation. Just like killing someone is normally perceived as evil, but in certain circumstances it's justifiable and there for would not be considered "evil".
Since morality is so subjective I think it'd be hard to define anything considerably "evil" or "good".
In example, what if a man steals bread from another richer man, to give to someone more in need?
Some might argue that stealing is wrong, so the man did an evil deed regardless of his motivations for doing so.
Others might argue that this man did a good deed by giving something to someone more in need.


I feel like it's way too foolish to really try and pin any sort of idea on something, and turn it into a good or evil being/force/thing/what have you.

Granted my personal opinion on god is:
I think there may or may not be something out there, something we don't understand but it isn't some omnipotent man floating along in a cloud arm rest. I surely cannot believe in any "god", especially one personified as a "heavenly father". That seems all too human if you ask me. I think there may be rules to the way the universe works, and maybe something there to keep the universe from completely spiraling out of control... But is a "god", I don't believe so. I believe it'd be more akin to energy/rules/laws/and physics. In the end I believe anything is possible, but almost none of it is probable.
