For example, he might be even more of an expert in potion - making earlier on, as he wouldn't have to spend time on other Hogwarts - required subjects. Also, his view of the wizarding world might be more positive as he wouldn't be exposed to the same in - house rivalries and politics at Hogwarts.

Snape's character would lack the strong connection to Hogwarts that defined him in the original story. Without the influence of Hogwarts' professors and the house system, his sense of identity would be different. He may not have the same internal conflict between his loyalty to the Dark Lord and his love for Lily, as the events that led to this conflict at Hogwarts would not have occurred. Instead, he could form different loyalties based on his new experiences outside of Hogwarts, perhaps to a different magical community or a group of independent wizards.
