[SPOILERS S2] He should just end himself

I’m on season 2 episode 8. It’s getting really annoying. Everything that everyone is doing is just making things worse, especially jonas. He should just do the noble thing and do what his father did since he knows his future self is the reason why all this is happening. No future self = end of loop. Simple, but no everyone has to get up and do something they don’t even understand because someone from the past or future said they should. It’s madness
