10 Times Batman Was The Villain
7. Various Murders & Torture Against Villains
Murder and torture is wrong, and not heroic in the slightest (if you didn't know that, perhaps have a friend check your basement).
Batman is known for his brutality toward villains, and most of the time it can be justified - he's simply using the requisite force needed to incapicitate individuals with superhuman abilities. Other times, however, it cannot be so readily explained away. In certain cases, the Bat has gone a tad too far in his use of force, horribly torturing and killing villains, or even just lowly henchmen.
This isn't limited to kooky stories like the aforementioned All-Star Batman unfortunately, with the prime universe Dark Knight being equally as guilty of such heinous acts (which you can find here).
