I'm going to defend this family
What drives you to want to defend them?
I do because they are kind to me.
It sounds like they have been good to you and you love them.  Wanting to protect your loved ones is a noble goal.  I hope it works out well for you!
Thanks, I did it. I just beat the shit out of a guy, who touched the family.
While violence is not a good answer sometimes it is need to protect the people we care about. You should be careful though you don't want them to get more hurt in your enthusiasm in protecting them.
