I like Byron, actually. He was justified in his actions -- he was a revolutionary fighting for his people against a power structure that was profoundly oppressive against Human telepaths (except for the small elite of telepaths at the top of the Psi Corps, who were just as abusive to their fellows teeps under them as non-telepathic Humans were).
Sheridan had a major blind spot for his own anti-telepath bigotry, and the Interstellar Alliance should have interceded to find Byron an uninhabited planet for his folks to establish their own world on, as they wanted. Especially given the decisive role telepaths played in both fighting the Shadows and in fighting against Clarke's forces.
He doesn't know how blackmail works.
"I have your secrets, that you'll kill me to keep secret, so I'm going to have a hunger strike until we die of starvation. By the way,
POLICE I
MINDRAPED ALL THE POLITICIANS!!!!! All of them, so even though I have the Alliance by their short and curlies (Do MInbari have bone crests around their junk?) you should come down below and arrest me, or kill me, or try to kill me before I commit suicide before anyone pays off our blackmail demands, that we did not actually formalize with anyone specific, because we are going the sympathy route, hoping some one will give us a planet, as we skip meals between our 14 hour long orgies, and then kill ourselves with fire."
Way before all of that, Garibaldi said Byron was a Martyr.
That means that Byron's plan was always to inspire through suicide.
He was never going to save the day himself.
Did Byron know?
Was he surprised when he killed himself?
Was he so dumb that he couldn't see where all this was going?
Then there's Lyta.
She sold sperm to the Narn.
Endless barrels of jizz.
And they gave her a planet.
Well, an explorer class spaceship, but she wasted a lot of money on the telepath war, because she hadn't figured out what an asshole Byron was.
Lyta could have built their colony, and lived happily every after, if she just ignored her dead lovers very beautiful hair. Instead she blew up at just the right moment to make humanity relent and let her people go.
Do you think she was a literal bomb?
Concussive force?
Or could she put a "command" into the heads of a billion people at the same moment that they could not ignore. Whether that thought was "free us" or "kill yourself" really depends on what sort of day Lyta was having.
