No.. It's a very common programming concept. You open a file folder.. all the items in the file folder are 'children' of the parent folder. It's the same with running processes launching child processes. The terms for ending processes abruptly all sound like murder. There's lots of commands embedded in different operating systems such as 'kill' 'terminate' etc.. If your process is using a dangerous amount of memory (about to cause the whole system to lock up), it needs to kill some of its processes or it will crash similar to a Windows blue screen..
