Should damaging units be able to targets both sides? Should there be an option to not use active abilities?

So far of bronze units only Skellige can attack its own units to set up scorch/remove cow carcass/etc. This is clearly due to self harm being a theme in some Skellige decks (berserker/axeman), but is it really necessary that other factions shouldn't be able to target there own units? I think it would be great and helpful to counterplay scorch/igni/rot tossers and add more strategy to the game. However this may be problematic as currently you are forced into using active abilities even if you don't want to.

Do you guys think these would be healthy for the game or not?
