No, this is real growth; or rather, the beginnings of it. As the MC's said himself before, his past self was not without flaws - he was too single-minded, and let his aunt die. Rather than simply rely on his knowledge of the future to get his way, he must become more than he used to be - because he now has the opportunity to correct all his past mistakes, and more than just have a meaningless revenge, he can create a better future. He's just starting to realise that he can be more than a simple villain, and although that undermines everything he considered part of his identity, thus creating this crisis, it can lead to real growth. It's a really well thought plot development! Just hope they don't screw up the execution.
