Kingdom Spoiler! Why was [redacted] going to shoot [redacted] at the end?

Last chance to avoid spoiler!!!!!

Why was May going to shoot Noa at the end? What purpose would she have in that? Seemingly take a long detour on her way back to the humans to deliver an extremely precious item just to assassinate Noa who helped her? I mean obviously she is anti-ape which is why she had no problem double crossing Noa and being the direct reason his entire clan (almost) died. But again... she has this super important computer chip thing why risk getting caught/killed/etc just to shoot Noa? I mean in her mind she probably thinks Noa and the Eagle Clan hate people now (rightfully so) so maybe she wanted to kill him before he had any ideas to attack people? But he made it pretty obvious he just wanted to bring his people home and get back to normal life...

Makes absolutely no sense to me honestly but I will say it made for a great emotional scene! What are your thoughts?
