If one targeted creature becomes an illegal target, the other will still get -13/-13 until end of turn.
Ruthless Disposal
You can’t target one creature twice to give it -26/-26.
Discarding a card and sacrificing a creature are both part of Ruthless Disposal’s cost. You can’t discard or sacrifice more to target more creatures, and you can’t cast Ruthless Disposal at all if you don’t have any other cards in hand or if you control no creatures.
