Nope.
He was a shit character with shit motivations in sonic adventure.
When you kill a character they can't learn, shadow actually learned how to be a better person. And changed over time.
Something most sonic characters, including sonic himself fail to do miserably. They fall into archetypes , shadow actually changed his feelings on things.
Also shadow is popular so, the he should have stayed dead mentality is essentially some child yelling at other children about enjoying their toys. " how .. dare you en masse like this character necessitate his existence , how... dare you "
