Ever? A 50-year old who punched a bully when he was cornered at 20 years old, 30 years ago? Not saying that's great behavior, but perhaps understandable after having been cornered.
Or at 15? 10? 5? Somebody who at 3 years old kicked their older brother of 6 with a bunch of legos? Not going to hire that maniac? Do you yourself have a job?
