He does try to explain himself, and then a reckless and irresponsible decision that could have been avoided - again - killed a bunch of civilians(also again?) and presumably also Lizzie.
To me, the way JD was shown up until Act 1 ends basically points all to one thing - a feeling of wanting to prove his decision making and leadership skills when he should just do the job, and/or justifying his acts, although the whole thing about the protesters is uncertain on how the best way to react was, to me. The jammed rocket silo doors on Azura, the Hammer of Dawn strike when they should have focused on efforts to draw the fire of the Swarm while covering the convoy and obscuring it from the Swarm(they have to have some kind of smoke grenade on them, right?), or even just calling in more DB reinforcements as a distraction and hoping no Flocks suddenly show up, while some of them go help Lizzie’s Minotaur get free from the rubble.
