I mean, I'm not defending Bruce lashing out and attacking someone who cares for him, who is also suffering from a death in the family. But Dick's an adult there, even if he is still on the young end. That *is* better than hitting a child.
I said it wasn't an excuse. But he's still dealing with the loss of a child he was responsible for. A parent grieving the loss of their kid is allowed a little leeway, you can't expect them to just act normally after something like that. There's tons of other examples out there where Bruce has hit one of the kids when he wasn't dealing with the trauma of a lost child. Bruce is still a d-bag and abusive to the kids. It's just that in this one particular incident, it's harder to hate on him, considering how fresh that wound was. There's still no excuse for it, it's still unacceptable. But it's more understandable.and I'm pretty sure he was barely out of his teens when that happened. Bruce's mental state isn't an excuse and frankly doesn't speak well of how he deals with stress if that is his reaction.
