Sounds like high functioning autism. I am HFASD and my two youngest kids. Lots of experience here, as well as, with other ASD families.

Although many boys are not actively taught how to identify and resolve their emotions too. There's also that. Or a combination of both. So many grow up just feeling "something" but unable to identify anything beyond the basics: loss, afraid, pissed, cool, excited, etc.

It's also not unusual for early pre-pubecent boys to not feel guilt about doing what they felt like doing. I hate to say they don't give a damn, but that early testosterone jacking boys up, is certainly something unique.

This is the one argument I have in recognition of gender. Hormones make us all quite different. Even a boy with lower testosterone is going to have a stronger low-end emotional reaction than one with higher testosterone.

Also, not all bullies are angry or have been traumatized. Some kids are just a$$holes. Little boy in the park told my daughter she was pretty, and then kicked her sandcastle. It's corny but it worked. She chased him and thought about him (in a bad way) all day. She'll never forget him. Mission accomplished?
