I believe I actually would kill him if he'd done anything like that to someone I cared about.
Same here, my mum is disabled.
She's got crumbling bones, a kidney conidtion, sciatica and osteoporosis in her spine, a crumbling jaw and a whole heap of other problems which I won't go into.
She gets tired easily when out and needs to rest if she does too much... and my first thought was what I would do if I found someone had done this to her.
