I mean, scientists for the Manhattan Project were remorseful after the fact at least. In general though, scientists are primarily driven by curiosity with little regard for the safety of themselves or others. If IRBs didn't exist, I assure you that some experiment of dubious ethics would be in progress right now without it even occurring to the primary investigator that it might be morally problematic (it's important to note that with some researchers, moral issues just don't click mentally and there's not a question of malice). Even with an IRB, you still get studies like the Facebook mood manipulation fiasco at Cornell [0].
