You know that EK changed more than once stuff in the game around when she saw the need. Seymour 2021 might have been so, but going by the flow of several paths plus the new update, I doubt that the character card of Seymour 2024 looks alike.
Seymour is evil. The blackmail was the last straw for Seymour. He blacklisted Lena in all her jobs, from modeling, restaurant server, and sex work online so that Lena would be financially isolated and would be forced to work for him. If Lena still refused to work with Seymour, that is when the blackmail happens where Seymour reveals it was him who blacklisted Lena. If you consider those actions as "amoral" then I would suggest reflecting your moral system.
Spoken like either an a)idealist, b) activist or c) a guy with a board before the head. Since you simply state the Seymour is evil, no evidence, it is just your opinion you try to sell as universal. I know discussion today often boils down to such shenigans, especially in this thread, but you know what blows this "agrgument" of yours out of the water?
There are paths where the blacklisting has zero impact, does not come up at all or does not happen. In these game universes Seymour is nicer than in others.
As for morals, I am a cynic since I have been around for a while and I have seen some things I would have liked not to. Additionally, morals are also varied around the world and stretchable. So please no more attempted moral grandstanding and showing off limited life experience.
I know ther is a faction of players who will neverlike/accept several game characters and attempt to spread hate. If you really believe Seymour to be evil, you simply show that to quote Bachmann turner Overdrive "You ain´t seen nothing yet". Seymour is not a good guy, but he is also not evil.
