"Ask forgiveness rather than permission" is not equivalent to "forge ahead without thought for the consequences". Completely rewriting a codebase by yourself to show up a team that has been working on it for a long time might mean better code, but it's also a direct demonstration of the ineffectiveness of that team. Of course some kind of major shake-up is going to happen after something like that. Firing people might be a little extreme, but you certainly have to expect that it's a possibility. If you don't have the stomach for directly causing people to get fired, or for conflict, then don't go out of your way to demonstrate how poorly they're doing their job. Find your way out to something else, and let them do themselves in.
