Maybe Kirk was afraid, Mitchell would ultimately become so powerful that he could force starships to come to him regardless of a quarantine zone ... or escape from Delta Vega some other way.
Or Kirk just had "issues" after Mitchell killed Kelso.
I´ve always wondered, if Mitchell was killed at all. When that rock fell on him he had already regained his power. And with his power present, not even a blast from a phaser rifle could harm him.
Just a thought ...
There had to be some cap on the power as the crew of the Valient did not end up detroying the Galaxy so his power must have stoped growing at some point.
