No idea. Just throwing out ideas. If he always had a high amount of spiritual power compared to other humans, then he'd be a prime target for hollow attacks, meaning his original motivation may have been nothing more than survival.

We have no idea what exactly sends someone to hell, as our only example from the manga was a serial killer who was indiscriminate in his actions and took great pleasure in the act of killing.

The only other example we have of the actions that cause a human to end up in Hell is Kokuto, who is known to have killed a number of people, and gone out of his way to inflict suffering on others, with no sign of remorse.

Two people who were sent to hell for very similar reasons doesn't give us too much to go by in terms of working out what does and doesn't get someone sent to Hell, but apparently Kugo wasn't evil enough to go there.
