I tinks Snape is loyal to Voldermort because #1 he is head of the house of Salazar Slythern nd Voldermort is his heir. #2 His least favorite students ae the one who try to destroy him every year. #3 In the second book or movie he pulled Malfoy right back up to fight Harry in the deuling Club. #4 His Favorite student Draco Malfoy is the son of a Death Eater. Does anybody else agree?
