I've probably written this before, but Will Riker was promoted to Lt. Commander because of his actions while evacuating the research station. Yet Tom Riker was never granted the same promotion since he's still a Lieutenant when we see him in "Defiant". No wonder the poor guy was so bitter.
I know I've said something like this before lol, but love to chat about it
Will likely got promoted internally, via a citation from his CO, who was probably in no position to offer the same to Tom similarly, as neither are serving under him/her anymore. The abandoned Riker essentially becomes the "other", 2nd Class Riker thereafter, in just about every way, as wrong as it is.
Additionally, when we get back to him in "Defiant", it's after the events of the Pegasus scandal, which Picard admits is going to damage Will's reputation some, but that Will had years of excellent service to help him weather through.
Tom, at that point on the Gandhi, has no such service record of saving Earth from Borg etc... to support him, only one act of forgotten valor, lost years of falling behind his class, & an unearthed mutiny scandal, which probably stymied his career prospects even more than just being the "lesser" Riker. If anything, Tom is the Riker who
didn't voluntarily come forward about it, sullying him more than Will.
So not only did Will steal his identity & life & all manner of prosperity, like an improved relationship with his dad, he also somehow managed to unwittingly keep torpedoing him. He even marries Troi eventually, probably while Tom's in prison
It's not just sad, it's bloody supervillain birthing tragic. Kirk did less to Khan to inspire wrath lol, & Khan kind of deserved it. I might not go so far as to want to murder Will, if I were Tom, but I couldn't help but imagine how better my life would be if he
were dead
