Well I would prefer to not have either party die -- I'm not quite ready for Jason to deal with ACTUALLY killing someone and I would prefer to not have him die either. But Jason is stated in canon as being very durable and strong (able to go toe-to-toe with some of the minor gods and titans at least for a few rounds). So we can go pretty heavy too without Jason dying.

I just really want Jason to have a fight and then snap out of it and be like "oh gods I just tried to kill a friend" kind of deal and have some flashbacks to conversations he's had about losing control and how most of Jupiter's sons tend to go out that way (ie Hercules)

Reminder that there is also lightning and wind to deal with in a Jason fight.
