I broke a toilet in a church once....the only baddish thing i've done and to me it wasn't bad it was justifiable. My kitten was poisoned, brought it home threw up, one of the dogs cleaned up the sick and also got the poision, so we lost them both. We knew who it was but could not prove a thing, so in the early hours of the morning I snuck out of the house went over to their place and trashed their garden, plants, flowers, gnomes everything.
When I get worked up I have a very bad temper, and I love my animals. I was about 17 at the time.
