One of the reason for Deadpool mind being like that is due to his illness and healing factor, both keep destroying and regenerating his brain, not helping his normal self at all xD. In one of the comics, the Skull copied Deadpool healing factor to have undying soldier, they exploded due to the healing factor acting as a cancer and generating too much flesh.
To be exact je always regenerate/create cells without end but his cancer balance that by killing as much has he create
