Yeah, I understand what you mean, people do change, but since we don't know him personally we don't really know if he's changed or not. With family or someone close to you can see if they've grown as a person or not a lot if the time, and even then sometimes it's just for a little bit or just for long enough to get what they want from you. I've had people like that in my life, where they've claimed that they'd changed, made a show of being "changed" for a bit and then reverted back to their old self.
So far I haven't noticed anyone rushing to his defense, I may have missed it though.
I agree with what you put in spoiler tags. (sorry, I'm on my phone and sometimes it's easier not to reply with quote and your post is right above mine, so I figured I'd just reply like this. Typing out spoiler tags is also a bit annoying on my phone.)
