trtr states that as long as you know how to use Angel Halo properly you can use it to both kill and seal(Luka just doesn't want to kill, obviously). Though in Promestein and Black Alice's case I don't think Luka killed them intentionally so much as it was a side effect of taking the White Rabbit and their bodies couldn't sustain themselves after they ran out of energy.

Also you're underestimating how many angels Heinrich killed. Luka sealed like maybe 30 or so. Heinrich killed over 600. The majority of the holy energy that makes up the Angel Halo was because of all the angels Heinrich killed and it didn't have nearly that much when he first started using it.
