Sounds like you've got it all figured out - all feelings, actions, thoughts, and beliefs are generated by a chemical reaction in the brain, and that people who live good lives are only doing so for the "addictive" reward they receive from those chemical reactions. You know exactly what is going on in other people's heads and hearts, and everyone is the same.

Now, listening to that description of what you believe, are you sure you still want to advertise your mindset as such? I would wager no, but by judging your level of animosity for no reason, I might be proven wrong.
