YES HE WOULD SURVIVE. How many times do we have to go over this same concept? Go back and read the rest of the thread. Deadpool is immortal because Thanos cursed him, it has nothing to do with his healing factor. Would Deadpool's body be destroyed beyond regeneration if he was thrown into the sun? Yes. But would he be dead? NO!!!! A new body would simply pop up on earth and his soul/personality would inhabit it. No ifs ands or buts. HE IS IMMORTAL.
