It's a stupid move? Yes. Is it most likely anti-Town? Yes. Are the odds of hitting scum pretty damn low? Yes. (I was a suicide vig on MMMM:HR, and I would have won if I had vigged scum. Didn't shoot N1 because the odds were terrible. Then scum shot me. /sob story)
Is it a modkillable offense? No. The player may be really convinced he's hitting scum, or someone who claimed vig, or someone who is a huge distraction and is hindering the game at large.
And
why on earth would a vig shoot an Innocent Child?
Of all the ridiculous hypothesis... What if the Town lynches the Innocent Child, what then?The point is, you're proposing something that no sensible player would ever do. Shooting/Lynching a known Innocent Child
is
playing against win condition, but no one does that because it's utterly idiotic
.(Yes, yes, caveat for stupidity and trolling. Why are you letting those into your game?)
