We all know how strong Snape is. But I don't think emotionally that strong, despite his Occlumency. And now I'm just theorizing, but what would happen if he could get the Resurrection Stone?! Not the happiest ask, but I was thinking since a long time and just couldn't hold myself back anymore. He would break if he could see Lily again and imagine with Dumbledore too?
Mmh I genuinely think he'd never touch that. First of all Severus respects magic and has a very good understanding of the dangers of it thanks to his love of the Dark Arts. He'd know it wouldn't really be her. He'd be tempted tho... put the stone on his desk when he's an adult and he'd store it away immediately but I think he'd be struck in place mid-movement by a voice in his head whispering Lily's name.
But I think the mere idea of seeing her again would absolutely tear his heart open and unleash a torrent of pain and self-hatred that he's not capable of handling. Also even if he misses her so much he'd be TERRIFIED of what she'd say to him. And all of this isn't enough to balance the perks of seeing her face again.
He knows he's not strong enough to handle some of his emotions which is why he's been occluding from a young age. So I believe the mental wall would hold, even if it takes a big effort from him at the moment. Then he'd remove the stone from himself completely.
Same with Dumbledore.
But a post first-war Snape, striken with grief would do it I think. Out of despair, love and his deep need for self-punishment. Not sure he'd survive it. Well depending on what Lily would say.
