Furthering this point - I feel like this debate is rather similar to the one about whether trapping David in rat morph was really "better" than killing him. This action is technically non-violent, yes, but yet you could argue that the trauma caused by this is far greater than if they had just killed the Yeerks.

The Chee may have good intentions here, but like with Cassie you can argue that this good intentions sometimes lead to much harsher consequences.
