We create rules and then when people break them, we say (depending) law breakers are evil. If we created a law that promoted murder, then "according to the law", humans would not be commiting crimes.
We commit evil (if you like) acts. Its only evil because we have laws against it "and" it affects us personally to where they sre not Just Acts but they are Evil.
Point: Evil is a subjective word.
Hilter, for example, commited "bad acts" (evil, harsh, terrible, whatever) but he didnt create it. Why is it bad? According to who? Its bad because we base it on our moral code. The Nazi would think it perfectly acceptable for the "acts" they did.
Evil is such an abstract word. I dont use it because its surreal.
