Other forms: perpetrated; perpetrating; perpetrates
It's possible to perpetrate a good deed, but not likely. That's because perpetrate means to commit or be responsible for something — usually something mischievous or bad.
If you manage to slip a whoopee cushion onto your teacher's chair without her seeing it, then you've perpetrated a classic prank. But if you were to use your wily ways to break into the bank's safe, then you would have just turned yourself into "a felony-class perpetrator." Do yourself a favor and stay out of trouble!
