Sevarite reasoning methods seemed very Lawful and maybe like a missing piece of Irorism up until that point. He has no interest in Evil, if that's all right.
He is studying to be a monk, and if he were competent to do anything would be a more powerful monk.
...it was sort of the new thing and he was bored? He would not usually say this to an up-and-coming deity but the Sevarite faith teaches honesty and not to punish honesty.
If he could do anything, he'd ascend to godhood like Irori, obviously.
Carissa Sevar sounded like she was actually going places and doing things, unlike a lot of monks and priests around here. If you condition on 'sticking around Indapatta' you get some pretty uninteresting monks and priests, in his own opinion, except for a few very high-ranking ones who don't have time for him. He feels completely vindicated by the fact that Carissa Sevar actually showed up here in person. That said he's got, like, zero interest in going to Hell, no offense.
He'd travel the world killing things that ought to be dead.
With a few exceptions, like the pregnant lady who just left, men never do their fair share of the infanticide and it's always just the women who end up in Hell. She's got no realistic way of buying her way out from under that, now.
If she could do anything, she'd be rich enough to buy herself an Atonement, and do the same for other women who had to kill their babies when they were young.
He's always wanted to be Evil, and would totally be Evil if there was any acceptable afterlife option you could get as a result.
If he was competent to do anything, he'd conquer a country, rule it as a tyrant, harem, slaves, all of that.
