I might give Rukia a break from depressing conversations for a while, she listened to a loooooooooot of them last month. Still threading them out! But once she's more emotionally recharged, absolutely go for it.

Ellie and Umiko are probably of a similar mindset, then. Her ultimate goal is to assume political power, likely in Aqures Ixen since their monarch is absent and needs a replacement. So if heroes aren't doing their jobs and saving people or protecting things, they deserve no mercy. She thinks she'd do a much better job of ruling this kingdom and getting shit done.
