Alice kills all the monsters that directly oppose or threaten coexistence that Luka is unable to seal (she kept Spider Queen in check, killed Cassandra, killed Beelzebubs, aaaannndd so on) and Luka makes it a chief point of philosophy to always fight for the weaker party. Alice and Luka love one another which gives Alice reason to withold herself from violent reactions to any problems, while Luka's philosophy will make him seal Alice if she ever did.

But 'tis the internet and the possibility to convince someone even halfway is so low I wonder why you even bother trying to enforce your views on everyone here. It's pretty clear you don't intend to ever accept any explanation we give you, so why do you expect all of your "Alice is so evil and Luka's her hoe" shots to convince us? o.O

"Luka is powerless without his spirits and isn't supposed to use his angel powers much. Ilias saved him from destroying himself the first time, but she's not around to do that again. He also didn't face a serious 4HK or 4HK at once and even Alice wasn't really trying to even beat him."

The Four Spirits confirm that their pact with Luka is much stronger than the one they've had with Heinrich, and nothing broke their bond this time like before. It's pretty possible Luka can easily re-bind with the spirits or even summon them at will.

Luka+4 spirits as he's now is stronger than Alice or any of the Heavenly Knights save for full-release Tamamo most likely. And then, while needs to concern himself with not abusing his angelic powers most likely, that's what he's got to watch for :abusing. A single Daystar to blow up an annoying monster (well, seal it) won't cause him any harm honestly considering how much he had to spam these powers earlier to get to the point where Illias had to intervene.
