I've been considering to implement killing threads several times for the last 15 years (I think about it once every year), and every time I give up because it's too complex and just not implementable. To start with, a simple flag in the thread won't do any good. It will not cancel blocking system calls, so people will complain that the threads they meant to cancel continue to run forever. Instead, you have to use some facility to interrupt blocking system calls. You then have to convince callers of those blocking system calls not to retry when they see that the first attempt to call it was interrupted. And so on.
