joker has friends who rely on him and accept him for who he is and gets to be a hero.
goro wears "masks" to be accepted and only receives hollow acceptance by people who don't know the real him. he plays pretend hero and wants people to rely on him and see him as necessary instead of garbage to be thrown away but he only receives anything resembling that through another hollow relationship with shido.
goro is also too deep into his own shit with shido to get out without consequences of some kind, most importantly (to goro), losing his reputation because all his accomplishments are fake because he created his own cases to solve.
and that's why he didn't want shido to get his heart changed. he would reveal that or it would get discovered if people dug through everything involving shido's conspiracy.
basically, taking the conspiracy down means goro is going down with it.
and also shido has ties with the yakuza so even if goro did try to get out he probably knows he'd be killed.
and goro also loved shido because he was the only one to treat him as special, even if he did hate him at the same time. so goro didn't really want to kill shido either i don't think.
and i think goro thought shido was the only one who even could accept him for who he really was, which is what he wanted most. being a throwaway bastard child isn't desirable in japan which is why goro wears "masks" to be accepted. and who better to accept an unwanted bastard orphan like goro than one of his parents?
i think that's why goro was going to force shido to accept him in a weird way that also simultaneously included getting revenge by blackmail i assume.
joker gets to be free and have everything goro wants while goro gets to seethe and not fully understand what is even wrong with himself.
