In Psalm 22:18 it says "For dogs have surrounded Me; the congregation of the wicked has enclosed Me. They divide My garments among them, and for My clothing they cast lots.”
It was a prophecy that was being fulfilled even in the act of Jesus' death. Besides that, the Roman soldiers probably were just making a game out of an everyday situation for them.

Getting the possessions of an executed criminal was a pretty standard perk for soldiers of the time. It may not seem like much of a perk to us, but clothing was a significant expense at the time (as it is in many parts of the world today). 'Blood-soaked' wouldn't have been a problem. Things can be cleaned, especially if they were valuable. Just because you are a criminal doesn't mean that your clothing is rags.
A 'seamless robe' was actually a pretty nice piece of clothing, and well worth competing for. That also explains why they decided to cast lots rather than tear it into shares.
