Those are the hypocrites because they claimed faith in the beginning and then disbelieved after that, then they increased in disbelief and wanted sedition by that:

وَالْفِتْنَةُ أَشَدُّ مِنَ الْقَتْلِ

(and fitnah is worse than killing) (Al-Baqara: 191)

Those will never Allah (swt) forgive them, nor will He guide them to a way because they claim the faith by speech, whereas faith is a doctrine.
