There's a reason action movies don't zoom in on the awesome explosions close enough to see the dozens of innocent burn victims in the vicinity. Nobody wants to get dragged down by the plight of these nobodies.
But still, some action heroes take the collateral damage (and lack of concern for it) to a level that blurs the line between hero and villain, and probably wouldn't have looked so good in a court of law.
6Neo from The Matrix
If you ask any Matrix fan about their favorite part of the film, their answer will invariably involve Keanu Reeves's breathtaking performance as Neo. From the inspiring "I know kung fu" speech to his tender and heartfelt "whoa" monologue, his brilliant and multifaceted portrayal made Neo a compelling symbol of humanity at its best, alive and vibrant in a world dominated by oppressive machines.
Also, it was totally awesome when he killed all those guys in slow-motion.
So What's the Problem?
So when Neo's mentor Morpheus gets captured by the bad guys, Neo responds by arming himself with an arsenal larger than that of most developing nations, slaughtering a cluster of security guards before they can even draw their guns, before dropping a bomb on the ground floor of the building just in case there were a few errant cockroaches that weren't killed in the earlier carnage.
Wachowski brothers fans have noted the deliberate parallels between the messianic Neo and the Biblical story of the moneychangers in the temple, in which Christ pulled out a Beretta and killed about 50 security guards.
The thing is, it's explained early in the movie that there are bad guys who are entirely computer-generated (the "Agents") and then there are regular people who, when they get shot in the Matrix, die in real life. And those security guards were the latter.
Yet, for some reason it's played so that Neo is totally free from any guilt over killing a bunch of people, instead of just generating a helicopter and grabbing Morpheus from the top floor. You know, like they wind up doing anyway.
Or, if that wasn't an option, instead of walking in with machine guns, show up with canisters of gas that would render everyone unconscious. Sure it wouldn't have looked nearly as awesome as the guns, but at least it wouldn't have felt as wasteful (of both human life and ammo). So at the end of the day the lesson is apparently that it doesn't matter how many civilians you kill as long as you make sure that you look as cool as possible while doing it.
Of course, there's also the rationale that Neo was fighting for the greater good of freeing humanity from the Matrix. And thanks to the sacrifice he forced those security guards to make, their families could now be free to starve in a filthy underground city while being relentlessly pursued by killer robots.
