Both of these guys are false Popes or anti-Popes, in addition to being mentally unstable!
Firstly, why do you say they are false Popes or antipopes?
Is it easy to enter the list of Popes?
I'm sure those guys have broken with tradition, and that is where the mental instability comes in? Or are you sure 100% they have mental issues?
Secondly, you just judged two people to be false popes. Who are you to judge them?
Did you base your judgement on someone else's judgement and do the followers of those alleged false popes or antipopes agree with you?
Do we now have three popes like in the Western Schism? Then it is acceptable for anyone to have their own pope, and there should be no cross-judgment of popes.
