There is also the possibility of a Joker pushing somebody (possibly multiple to be sure) else onto the grenade, thus saving their life and causing destruction. Which has 2 possible out comes in itself:

1) Joker pushed another Joker or Cooperator. Which might be uncomfortable for a time, but would pass.

2) Joker pushed a Defectors, in which case some Defectors would want some form justice.

I have no numbers to prove this, just my feeling for the archetypes.
