That's because you're not a bad person, Allen. [That's why it's easier not to hate him, but don't try to make it like the Order is full of nice people who care what happens to people who get in their way.]
The Order only saves the souls because they have Exorcists to do it. If they didn't have Exorcists, they'd find another way to do it, and the souls...they wouldn't care about them at all.
