Actually, him becoming the master is exactly what Makarov wanted. He just didn't want it at the time because Laxus' attitude wasn't conducive of a master back then. After the whole Fighting Festival debacle, however, his attitude shifted and he obtained an acceptable attitude. Unfortunately, the rebel seemed to die with this attitude shift though. :/
