Being born a psychic in B5 is just.. Crap. Well for humans.
You either go into a .. Well Nazi type of group or put on meds that put you in depression ... Or run. .. Not the best of choices.
And if your a P10 or better your life is completely screwed.
And what Byron was probably thinking.. Got delt this shitty hand at birth, then more crap layered on.. Then oh find out your made by the vorlons for giggles. ..
No wonder he went loopy.
Anybody who's read the Psi Corps trilogy has an idea of just how much abuse the kids brought up by the Corps were subjected to. Brainwashing, gaslighting, constantly scared and pitted up against each other. No wonder he lost all common sense.
One sad thing I noticed when comparing the scripts to the episodes was that a number of small scenes were cut where Byron spent time communing with his people. I think people might have seen him in at least a slightly better light if those hadn't been cut.
