I find myself crying whenever someone else's child gets hurt, is this normal?

It always has that effect on me. Whenever I hear about a young child or baby abused/beaten, starved to death, molested or raped, etc I start crying... wishing I was there to save them.

At the same time, I have an intense hatred towards the pertrator. I feel like applying a triangular choke (sankaku), arm bar, etc to that beast and literally either strangle him/her or break their arm for doing that. That's the only reason I would happily use my self-defense skills... to finish them off if I had a chance to be in a room with them for even 5 minutes.

A couple years ago and till this day, the baby Addilyn case sometimes makes me have sleepless nights. I keep thinking of her and how she's doing. Her own father nearly beat her to death when she was just 3 months old. She's alive but with autism and brain damage because of that monster. I really want to destroy people like that with my bare hands but sadly that's not allowed. This is the case:

I'm a strong martial artist but yet whenever it involves an innocent child or baby getting hurt or killed by an evil monster, I get emotional, revert back to my girly side and start crying. It's like they were stabbing me many times. That's my weakness. I can't stand seeing any child hurt. Is this a normal reaction?

Sad part: While all these monster reproduce like crazy, I have a medical disorder that doesn't allow me to ever get pregnant. I knew that for years. I'm never going to give birth but I can adopt.
