Preach it brother!
Some people do evil because they are so lustful and greedy that in their rampage for self gratification they don't even notice that they hurt or destroy others.
Then there are those that do realize they hurt or destroy others in their efforts for selfish pleasure, but they don't care.
The worst are those who take pleasure in the destruction they cause to others.
All three are evil, of varying degrees.
A good person is one who is pained by others' pain, and therefore tries very hard not to cause distress or pain to others.
We all choose good or evil every minute of our lives. Every minute gives us another choice.
