Man does make his own rules.
I don’t have to respect you nor do I have to care about your welfare.
Correct. You don't.
You are nothing to me. There is no god to say differently.
While I don't believe in God(s), I don't affirmatively deny their existence. There may well be a deity or deities...I simply don't see any reason to think so at this time.
As long as I don’t get caught I can treat you anyway that I please including cheating and stealing from you.
Again, this is rather obviously the case.
If I don’t get caught there is no price to pay.
Another truism.
You don’t matter a whit, only what I think is right matters.
Incorrect, since there are real world consequences to your actions.
Wrong. Consequences are for those who get caught. I don't have to have compassion for anything or anyone. Only God says I do. You are a shining example of why society is failing. You believe in nothing but yourself and you are flawed.
