Worst role ideas?

This is actually a pretty neat role. Here's a little tweak:

Explosive Fruit Vendor

: Each night you may give a player a lovely Edible Arrangement. Little do they realize, it is a bomb! It is set to go off when every living player (other than yourself) has received your healthy, artistic, and highly volatile gift. Death by fruiting cannot be prevented or redirected by any means. If you succeed in blowing everyone to kingdom-come, you win!

Basically, it's like an survivor-finder. You plant the fruits on players you suspect are going to survive until endgame, and hope they do! Finally you wouldn't be cursing your ill-fortune at being in a game with lots of VIs who are too obv-town to lynch and too stupid to be night killed. Would prob have to be able to give multiple fruit at least on night one.

Not if you very strictly enforce that players must play to their win condition at all times.

You are a

Conway Cell

At the end of each Night phase:

If you have fewer than two neighbors who are Conway Cells, you die.
If you have more than three neighbors who are Conway Cells, you die.
If any player has exactly three neighbors who are Conway Cells, that player becomes a Conway Cell and becomes a neighbor with X randomly chosen players.

You win when at least half of all living players are Conway Cells.
