ehhh, unfortunately I've met more than my fair share of people who unironically like Stalin.
Lots of actually good communist figures out there and they go out of their way to choose the homophobic drunk domestic abuser who kept a literal child rapist as his right-hand man.
Trotsky is who Lenin wanted to take over the party after his death, but Stalin framed him as a power hungry authoritarian and took control of the party then forcing Trotsky to flee the USSR then had him murdered in Mexico to stop his criticisms of the USSR under Stalin's authoritarian reign.
