And in the early strips he routinely forced confessions from people by doing things like dropping them from heights and catching them at the last second.

Also, the radio show had him stealing a statue from a "primitive tribe" (I don't recall which one). It was valuable and the proceeds were to fund important medical research, but -- by today's standards -- his actions were nevertheless undeniably theft. When the tribesmen tried to reclaim what was rightfully theirs, Superman fought "the savages" off. I have learned to skip episodes which involve "primitive" cultures because Superman and the other main characters invariably treat the "natives" in a cringe-worthy manner.
