Firstly the hadith did state that Islam will be divided into 72 sects. Most of these sects have slight differences expect for the Ahmedi. Most people just call their selves "muslims" not "shias" or "sunnis". A good muslim will be the one who obeys Allah, a bad muslim will be the one who disobeys Allah. TTP, ISIS and many other radical groups are just using religious reasons for political power, their ideology is taught to the uneducated who are usually very gullible. Allah says those who are taught a corrupt version of Islam will not face hell fire, it is a muslims duty to correct them.
