He may still hold onto his core beliefs of right and wrong, but he also understands the need to look out for himself and his housemates in a more Slytherin way. This could mean being more selective about who he trusts and how he shows his trust. He also becomes more aware of the power dynamics within the house and the wizarding world in general. He has to use his new - found Slytherin skills to survive and thrive, which changes his character in a more calculating and politically - aware way.
