If anything, the almost-hostile-takeover Guy experienced by his more zealous counterpart was a much-needed wake-up call. For one, he realised that his previous life wasn't as impactful as he had thought it to be. Many achievements which he considered monumental milestones appeared to have been built on a foundation of sand.
'It seems that my accomplishments and initiatives were inconsequential in the grand scheme of things.'
Secondly, he finally recognised that this world was much worse than his previous one. Even with all the unpleasantness that existed in his previous world, at least the society there was coated with a sense of peace. While most people were selfish, there was an incentive to offer aid to others. That feeling of togetherness was missing in this world.
'Magic just makes things worse. Not only does it corrupt natural laws, but it also corrupts the humanity in people's hearts,' Guy concluded.
