Why didn't Quote steal the key from Jenka?

I mean, he did steal a gun from Gunsmith.
So, why not?

 

This is just a guess but iiii'm pretty sure it's easier to steal from a sleeping guy than an awake witch.

 

Theory: Since Quote is a battle robot designed to destroy the Demon Crown, it's very likely that he was programmed not to be evil, but simply seeking self-defense, the cost of which probably did not matter to him.

He stole the gun so that he would have some sort of self-defense. Adding to that, if Quote returned to the First Cave, it's most likely that he wanted to return the Polar Star, because, by that point, he had other weapons to use.
Also, judging by the dialog, he trusted anyone who wasn't a threat (Jenka) and tried to help them (by bringing the Puppies, in that case). That's why he only asked for the key and didn't just steal it.

 

Because Quote isn't a bad human robit.

 

Because androids understand morality (or at least Quote does)

 

Because Jenka didn't leave it in a chest. She probably had it on her? And while he can shoot near non-aggressive intelligent lifeforms, he is unable to target them unless they pose a threat.
He couldn't stop Toroko from being taken. And couldn't stop Sue from being taken. Can't even shoot Ballos until he makes an aggressive move.
If only the Doctor treated Quote nicely, he could have taken over the world.

yah that explains a lot like how the bullets can't harm NPCs. But why can Quote kill the one and only chinfish?

 

Anything that can hurt Quote can and will be brutally rendered into their base components through excessive amounts of firepower

Consider me slightly disappointed that you can't destroy spikes, because that'd make the Sanctuary so much easier...
