1. Do not see wickedness in others.Because you see outside what you're inside.This world is our mirror.
2. There is no sin.
If you'll go deeply into some one's affairs which you call "sin",you'll find that those are simply activities,actions,of purity.The doer does not recognise any impurity in his action.Otherwise he won't be doing any such.No man can do any impure act intentionally,knowing it to be impure.Every action is a step towards justice.
3. Don't call them criminals.They've just accepted it another way of life resorting to which they achieve their needs,these severely poor fellows.
Let evil perish from wherever it may have it's origin.
