I finally found the quote, here it is (for those who haven't read False Colors, SPOILER), (Also its on page 194)>.
'Tolwyn paused. "I'd just been assigned to the Weapons Development Office when Concordia went down. I inherited Behemoth from Ubarov, who had the post before me. Frankly, my first reaction was to scrap the damned thing then and there. The design was all wrong, for one thing. It should have been mouted aboard a ship that could defend itself effectively... and one that had some legs, to, so it could maneuver in a combat situation. Behemoth didn't have either capability. And I didn't like the whole concept of blasting planets indiscriminately, either. It always seemed to me that marked a difference between us and Thrakhat was that we had at least a modicum of morality on our side, and this was putting us on the very same level as him."'

"Exactly," Tolwyn said. "I figured the only way to head off a coup was to remove the only excuse the conspirators had. End the war by whatever means possible, and the civilian government wouldn't be in a postion to screw things up so much any longer. If I'd've known about Paladin's Temblor Bomb Project I would have thrown all my department's resources into backing him. But his operation was strictly black, top secret all the way."'
