Placing trauma on others just to handle your own trauma doesnt justify you. The author isnt trying to redeem him by showing us his past, just explain that this is where he comes from. He obviously didnt learn how to handle his anger in a positave way, but clearly using his fists helps and that is the only way he knows. He doesnt know how to care for people because hes never received care Beyond the teachings of his coach. Im curious how his his jinx and clearly s** addiction comes into place now
