Not so. A process being killed never automatically kills any other
process in the Posix process model. Process groups exist to make it
easy to send a signal to a bunch of processes simultaneously, so it
makes sense to put a daemon in its own process group. Similarly,
sessions (which consist of one or more process groups) exist to
regulate which processes get signals from the keyboard driver.
You don't want daemons to get those signals ever, so you put them
in their own session. But even if you don't do those things, the daemon
will still live on.

The peculiar excellence of comedy is its excellent fooling, and Aristophanes's
claim to immortality is based upon one title only: he was a master maker
of comedy, he could fool excellently. Here Gilbert stands side by side
with him. He, too, could write the most admirable nonsense. There has
never been better fooling than his, and a comparison with him carries
nothing derogatory to the great Athenian. --Edith Hamilton, The Greek Way
