As for my rpg experience, any kind of magic that harms the body or the mind or the possessions of anyone is forbidden. I don\'t think it\'s a matter of magic class or whatever, when I\'m a DM if a player tries to magically strenghten a comrade to help him escape from prison (they always have a little stay in jail

he will be arrested: even a \'Good\' magic can serve bad guys.
On the other hand, I once created a realm where the king was so nice to everyone and the people was so happy that everytime the king died he was brought back to life, and this served the \'Good\'. Therefor I think it\'s quite impossible to classify the types of magic.
But if you manage to classify them, I\'ll honour you as a kind of RPG God !
