I already hate this. Xavier is being gradually destroyed by each successive prequel. He's always falling short, and every new dilemma makes him look more incompetent. It wasn't an issue for me until Apocalypse. That film had him chastised by Raven for being naive and unprepared for conflict, something I didn't buy after his experiences in First Class and DOFP. It felt manufactured to give Charles something to learn and Raven some wisdom to impart.
But this scene? Oh boy. They've just switched places, and now Charles is so invested in heroism that he's putting his kids at risk? I'm not sure it would grate on me so much if it wasn't framed as though Charles is being a petulant prick. I haven't seen him written so unpleasently since The Last Stand.
