I think it's their responsibility to stop their son from murdering people. To stand by idly while he goes around hurting people and trying to kill their other children would be even more grievous.
In my opinion you stand by your child whenever. Your child should be above everyone in the world.
I just want to be clear I'm understanding you. You are saying Enji & Rei should standby Touya while he kills their other children and anyone else?
Not their children. Just i dont think they should fight him. They should protect him. Their children to them should be above other people.
okay, I understand what you are trying to express now.
Honestly neither eiji nor rei were ready to be parents. One was self absorbed goal oriented lunatic and other was just too immature. Dabi is an unwanted consequence of their inept parenting. And now they want to what fight him again? Rather than fighting they should be on their knees begging forgivness. They have no right to stop him.
