I am with you guys on the 'he needed a killin'.
I made the foolish mistake in my younger years to hook-up with a monster who harmed and killed a few of my pets before I caught on to what he was doing. He was a sweet-faced control freak who knew he couldn't hurt me, so he hurt those I loved.
Now, my animals are my family--- they have been there when the humans have let me down. I won't let them down if I can help it. 'nuf said.
So sorry for your loss...how horrible. I hope that monster gets what he deserves some day.
