They are not Jihadist, they are Not Muslim, They are Not Human. Can you Imagine that A man can Kill another Person, On the Basis of His religion?
Ali burnt some people and this news reached Ibn 'Abbas, who said, "Had I been in his place I would not have burnt them, as the Prophet said, 'Don't punish (anybody) with Allah's Punishment.' No doubt, I would have killed them, for the Prophet said, 'If somebody (a Muslim) discards his religion, kill him.'
Sahih al-Bukhari, 4:52:260
