Exactly, like the spider mom... Most beautiful death everAy, with you here I can use an example!
For example, in Kimetsu no Yaiba. We see the backstories of the demons and we also see Tanjiro sympathising with them and understand what led to them becoming what they are. However they are still unforgivable and justice has to be delivered.
That's what I think will happen with Orochi. We'll be able to sympathise with him but eventually when Wano gets heated much later, he will be brought down hard.
On topic, Orochi's death doesn't have to be a cruel one. He probably lost his way at some point and someone will remind him what he did wrong.
