I think it’s more accurate to say that his reaction led him down toxic rabbit holes that warped his opinions and beliefs into what they are now.

Obviously we’ll never know, but I’ve personally known people who’ve genuinely changed as they got lost down various paths. Someone who’s indoctrinated into a cult, for example, obviously wasn’t indoctrinated as they came out of the womb. They weren’t always like that, it instead happened to them as some point.
