The author definitely has a liking to Sid but I don't understand why
I believe it’s okay and he did deserve to redeem himself
Also I wanted to say Cain is also a fair and just ruler. So I do think based on his character and his love for Sid he wouldn’t have made Sid die or disappear u know!? And Sid at least tried to do something right before he died so these actions at least gave Cain a reason- maybe not that big of one - but a reason to at least give him a chance.
I don't think he deserved to redeem himself bc he manipulated and made the best friend go crazy but if it wasn't for that plot I'd agree with you. Cause then it would've been just Sid betrayed Cain but near the end he tried to help because he felt bad so yeah he definitely could've deserved the redemption. But for what he did for the best friend I just can't like him Not to mention he was very deluded.
But I do agree with the Cain part. He is a fair ruler and Sid is someone he's known forever/for a while so from his perspective yeah I understand why he gave him a second chance
He didn't deserve a redemption arc at all..Idc if his memories are wiped Like he's even looking after their kids? noooo
They could've just introduced a new character and let Ben be the one to kill him once and for all like he wanted to because if his betrayal to Cain
