[Marvel] Does the Hulk have a separate soul from Banner?

Soul in the most mystical, religious concept as possible. Are there really two souls inhabiting the body of Bruce Banner or is Hulk just an alternate personality of Banner spawned by gamma radiation?

This also raises some interesting scenarios:

* Assuming Hulk is indeed a separate entity from Banner, would reversing the effects of the experiment 'kill' him? As in: would that force Hulk's soul to pass on to the afterlife?

* Assuming again that Hulk has a separate soul from Banner, what happens if Dr. Strange extracted Hulk's soul from Banner's body? Does Banner get cured of the Hulk or is he now able to control himself when turning into a giant green monster? Or would this create two bodies: a giant frothing green man who calls himself the Hulk and a Caucasian male PhD in nuclear physics called Bruce Banner?

* During times when Banner and Hulk are in cooperation and Banner is able to control his green form, what happens if Ghost Rider gives him (or them) the Penance Stare? Would sins committed by Hulk alone count as Banner's sins and burdened upon him or vice versa or both? Does Hulk even meet the standards of sentience to commit sin?

* In the comic *What If Scarlet Witch Ended House Of M By Saying No More Powers?*, Wanda depowers all mutants and mutates in the 616 world. Is Hulk's personality considered part of Banner's "powers" and also get wiped out, or would only his ability to turn into a giant green man get wiped? Would Hulk then survive inside Banner's mind?

In the original comic, Bruce had more than one type of Hulk in him. Each Hulk represented a different aspect of his personality. The Green Hulk manifested most of the time but not always. So I'd say one soul with multiple personalities.
