What were the negative outcomes of the crusades?

ThE Muslims started a reign of terror against the Christians (infidels) that has continued until this. One of most recent atrocities committed by these people has been a series of attacks where Christian churches have been burned with worshippers inside. Muslims don't concern themselves with coexisting with other religions but say "join us or die". This is the reason that Pakistan was created by India who hoped that this would satisfy the Muslim's thirst for conquest. It did not but did, crate rogue state which is a haven for terrorists in the Middle East.
