I took as either
A) He was dying and desperate to prolong his life, thinking that separating his two halves would do this
or
B) He wanted to get rid of his human weakness once and for all, and V was a byproduct of the process, leftovers, if you will, which backfired when he became a fully autonomous person
Urizen's motivations are easy to explain - he just wanted the fruit to become stronger. V's are a little more complex. He clearly wanted to merge with Urizen in order to, well, stay alive in some form, but it also seems like he felt regret over not only separating himself to begin with, but all the heinous things he did as Vergil throughout his life. So it seems possible to me that he truly did want to stop Urizen, not only to prolong his life and become whole again, but also because he genuinely disapproved of what his demon half was doing. There does seem to be some desire for atonement in him, to a degree.
Upon becoming Vergil again he clearly no longer has any motivations of world domination, or homicidal tendencies, and even goes so far as to thank Nero for essentially saving his life and giving him his childhood keepsake. Vergil is still an asshole, but it's clear that his time as V influenced him in some way.
