To expand on the title more, is there an adjective for someone that is aware of something happening but is not doing anything about it, even though they could interfere but they're just not choosing too?
Here's an example: let's say that there's a toddler at a daycare. The toddler starts stealing toys from other kids and gets into fights with them. The daycare supervisors are completely aware that this is happening, and they can intervene, but they choose not to.
I tried the words ignorant and oblivious but that doesn't work since the person is aware it's happening. I also can't think of any other word that works. If someone could help, that would be greatly appreciated.
