The "other way" in the bad-or-worse scenario almost always comes down to "do nothing" -- which itself is a choice, though perhaps more morally acceptable than the other ones available.

Everyone has their lines that they won't cross. Some are so deep in "inhuman monster" territory that they might as well not exist; others have the strength of will and defined limits that get them upheld as saints (too often after their limits get them martyred).

Only you know where your limits are, and I hope that you never get pushed up against them in your lifetime.
