A large part of Batman’s persona is the fear it strikes into enemies’ hearts. For example, a costume resembling a bat was chosen so that criminals would be afraid of him. There have been times when Batman really uses his “scare tactics” to get information from criminals. I’m wondering, what is his code of moral conduct? Has Batman ever tortured someone for information? Would any of his scare tactics be considered torture (or illegal by a developed nation’s standards)?
In Batman wikia it lists an ability:
Intimidation: It is widely known that Batman has the ability to instill fear in others, even the people that know him best are intimidated by him. Even those who aren't afraid of the likes of Superman fear Batman.
Expert Inquisitor: Batman is adept in the use of interrogation techniques, employing anything from law enforcement methods to outright torture.
