Did mary deserve her nickname blo. ody, if so why

Mary was queen of both England and Ireland and was part of the Tudor dynasty and was the daughter of Catherine of Argon. She was given the name of "Blo-ody Mary" because she tried to re-establish Catholicism in England but England at the time was Protestant. So in order to rebuild Catholicism, she executed and did a lot of "bad" things to Protestants to get rid of them but it resulted in massive bloodshed. She ended up being killed through her younger sister, Elizabeth I because she was accused of trying to kill her when she was going to be her successor but it was suspected that the plot or accusation coordinated by Elizabeth's chief of security(can't remember his name) which Mary denied having a part of but it was her word against a loyal servant of Elizabeths. I won't describe how she died but i remember reading this in school:) Oh, ya, she definitely deserved the name.
