>>You are NEVER a former Catholic. Once a Catholic, your soul is marked forever. You are ALWAYS a Catholic and will remain ALWAYS a Catholic — answerable to the Lord as to why you stopped practicing your faith at the moment of your death.<<

No, think of it this way.
If you are baptised, can you ever become unbaptised?
