From 52 - World War III Part One: A Call to Arms, this is possibly the best insight into Jason's tenure as Nightwing. Violent, insightful but still maniacal.

Pre Nightwing: Year One, when Bruce wanted to give Jason a compliment he told him how like Dick he was. Plus all the meta on replacements and graduations, and Jason taking Nighwting's identity because he's taking responsibility for what's happening, thus making him the good son, makes sense in Jason logic.

You said it much better than I did. Especially if he thinks Dick has moved on, then natural progression would seem natural.
