OK, but what's your point? So the bully has a hard life. OK, yes, that's true, so sad (really, no sarcasm), but what do you plan on
doing about it?
Your argument often ends up implicitly turning into "Therefore, we shouldn't punish the bully, it's not his fault. Therefore, I guess, well, we'll do nothing." You've cognitively narrowed your focus to just the bully and forgotten everyone else who is getting bullied.
That's not goodness or justice, that's terrible. A very common form of terribleness that some people seem very inclined to, but I don't think it's ever just to get so caught up in the hard life of a bully or criminal that you forget entirely about the victims of the bully or criminal. I don't know what's so cognitively tempting about this point of view, but resist it.
To be clear, I'm not trying to secretly advocate for or justify any particular solution either. But there must be some way to contain the bullying; there's no value to anyone in letting one bad seed's poison spread.
