“A harmless man is not a good man. A good man is a very dangerous man who has that under voluntary control.” — Jordan Peterson
Self control is a good trait. The baddest man in the room never has to prove it, but should be able to defend himself and the weak when necessary. This is not just a bare knuckles statement. Being intellectually strong as well as spiritually sound are also strengths one needs.
None of these come for free. You must work on them, and work on them constantly. The world doesn’t stop and neither does evil. Now go out and be dangerous to evil.
