Technically all of the disciples from past to present needed therapy. The old disciples just got lucky coz they have Pietro to ground themselves from being too absorbed in the harsh world they live in. Although, all of them contribute to checking on their behavior and as much as possible avoided on inflicting more damage to innocent people. Unlike the current disciples. They were so hard on themselves and got manipulated by Raphael's sweet words.

The new generation of apostles are just kids needing proper guidance. They were just chosen and had met a very bad father figure. I just hope that under Peter they'll have that proper guidance and comfort they wanted to have. So sad for them
