I was thinking the exact opposite. If he enshrines “my closest friends, and those who died of my worst decisions,” then someone he burned to death seems more likely to fit in the latter category than someone who died for other reasons. If, say, Voldemort killed Narcissa to manipulate Lucius and/or to amuse himself, then I’d expect Dumbledore to regret this death but not to rank it among those he regrets “most of all”.
I did neglect the possibility that she was working for Dumbledore somehow. I probably shouldn’t, since that would increase the probability of Mor!Voldemort killing her in this way.
