Evil deadpool came into being when pieces of his body came together (that includes pieces of his brain) so i guess he'd just grow a new one after a while, also he's incapable of death since thanos cursed him to not die (some curse right?)

Technically they never say that Daredevil and Spider-man put his head back together. So the only thing left is to assume that it grew back. Cause otherwise, it'd just be making stuff up.

Deadpool Corp (can't remember the specific issue) had the big villain of that part of the arc say that even throwing Deadpool into a star would only keep him out of their hair but not kill him. Take that as you will.

I was thinking about this he has had his brain completely blown out of his brain grew back so what would happen if his head were chopped of would his head grow a new body or would the body grow a new head, I would think the body because of the organs and such. Also what if he were cut in two vertically would only one half grow back or would both , lol I can see him almost cut in two vertically and growing another head and third arm like that hot dog ads and wade segueing with himself or eating while killing people.

But if Deadpool can regrow limbs and organs, Why cant he just make another deadpool of himself. so you have two Deadpools (Sorry for bat English I am from Holland). :)

Okay, for starters, I read a panel where he's telling someone (I forgot who it was. Maybe Evan) to take his head back to his body before the body grows a new head. They have been instances where he has grown a head, so I'd say it's fair enough to say that he can, indeed regenerate a head.
The reason he usually reattaches limbs and heads and whatnot, is it's much faster than growing a whole new one. I think it was stated somewhere that it can take almost an hour or longer to regrow a head or limb, but reattaching parts only takes a few seconds to minutes depending on the size of the part.
His healing factor is partly driven by emotions, so the amount of time it takes can sometimes depend on how he feels.

As for the whole curse thing, I've seen people ask if he can be killed by destroying the atoms of his body, throwing him into an active volcano, etc. I'd say no. Even if you were to do something like that, you could destroy his actual, physical body, but not his soul. That's my take.
Any questions?

His healing factor is phenomenal, he can survive decapitation and even regrow limbs although he usually just reattaches them when they get hacked off.

He can also regenerate organs, and is obviously resistant to most drugs, poisons & toxins.
