My biggest issue with CHASM is that the foundation is a lie. Ben is delluded.
Peter didn't cause his problem with memory loss. Sense of Self loss or what have you. The Beyond Corp did that.
What Peter is "guilty" of is not trusting the folks who made the problem to correctly fix the problem. And he's not wrong, Ben should see that regardless of whatever memory loss he's incurred.
I'm calling it bad writing. Writing the ignores logic in favor of unnecessary drama/character assassination to further 'x' plot later.
