Depends what they've done mate. its hard to suggest stuff like that withough knowing more of the story (i DONT want to know more btw, i was just saying) i've done some pretty evil stuff but i justified it in my head at the time. looking back though it was daft and i would be in alot of trouble now if i'd have been caught.

supergluing their car up isn't fucking up their life though is it, its inconvinent at worst. i'm not suggesting anything though, but i do think that if you were serious there wouldn't be a thread about it on a public forum. If your that hell bent, just go and do something about it.
