Was wondering examples of superpowers that despite good intentions do harm. Like with Rogue, if she were to get close to anyone, they might die.

I don't think Magnus "qualifies" since he seems to be just Magneto Jr. And let's stay away from death touch characters because there is already a page for that,

Magnus has a lethal touch that can turn other beings into solid steel and kill them.

Generally speaking, and also of the largest fallout, reality manipulation abilities seem to end up causing more damage in the end in all cases then good.

But can you provide specific examples where more harm was done CATPANEXE?

Arguably Cyclops.

" in all cases "
