MDG/COA Question

I think that people naturally want to be good. in the story Rainsford didn't think hunting was wrong because he didn't understand what the animals were feeling. he also immediately thought that hunting humans is wrong. General Zaroff thinks that what he is doing is fine. He also thinks hes doing the world a favor because hes hunts the scum of the earth, sailors form tramp ships of any race.
I always want to be good and do the right thing, but i don't always do the right thing. No one is perfect so we make mistakes, but we always want to do the right thing. To be good you also have to want to be good. When my parents want me to do something for the most part i always do it but some times you just get lazy and do the bad thing by not listening to them and leaving what ever it is undone.
