I mean, I'm sorry he had to die, but he wanted to be Praetor and he also nearly started a war between the Greek and Roman camps when we were in the middle of trying to defeat Gaea and save the world. I guess you can't fault him for being ambitious, but he doesn't happen to choose well. A lot of people were being manipulated by Gaea and the gods were kind of split in half most of the time, not always themselves. Greek and Roman sides warring with one another about who they should be. It was mostly Juno's fault. Hera if you're Greek.
