It's seems to be a vallid trope that could be considered bad writing and therefore maybe shouldn't be cut, though the description could use a lot of work.
Mark Lungo: I think this is (or was) a Sub Trope of Thou Shalt Not Kill. The essence of the trope is hypocrisy: the hero makes a big show of never killing his/her enemies, but then does it anyway. Thou Shalt Not Kill is about the trope being played completely straight.

Mostly the trope was the original author bitching about Batman. Seriously, every single example was Batman (well, okay, except for one about Doctor Who), and worded deliberately slanted to make him look bad. Like the ending of The Dark Knight, for example. What actually happened was Batman tackled Two Face to stop him from shooting Gordon's son. The listing on this page was more along the lines of, "Batman hurls Harvey to his death," trying to make it sound like he was a villain.
Oh, and it started off with a political jab, too, which was entirely unnecessary.

Okay, so maybe the original version was poorly written. I still think that this is a valid trope. It just needs a rewrite and some non-Batman examples (I'm sure they're out there).
