Question

It was _____ who said, "the massive threats to human welfare are generally brought about by deliberate acts of principle, rather than unrestrained acts of impulse."

Answer 1

I believe the answer is: Bandura

Bandura is a famous social psychologist who is known for his studies in social cognitive theory, therapy, and personality psychology.

Through that quote, Bandura intended to infer that the threat that come from deliberate acts of principle tend to be more massive and more organized, which make it harder for the perpetrators to realize that their actions are wrong.
