I never really understood why Venom wasn't depicted attacking Mysterio and Vulture during his vendetta. Maybe Marvel might have ignored that like you said.

And the reason that Sandman had fell apart after Venom had bit out a piece of his mass was because Venom had used a deadly, poisonous bite.

Sandman's remains got washed up onto a beach and he tried to restore himself using the sand on the beach. But unfortunately he couldn't hold himself together any further and soon exploded, where his sand soon reformed into four separate forms. His good, bad, innocent and gentle personas all manifested as full fledged beings. But when the bad Sandman had merged with both the innocent and gentle Sandmen, the good Sandman refused to merge back with him and soon disintegrated into lifeless sand.
