I am reading perldoc.perl.org and am not understanding exit and die

If I have a conditional in a sub that I want to validate with, what is
the correct way to do the following:
1. End the sub and return back to the script without continuing
that sub.
2. End the entire script without *any* further execution.
How do I write this?
snip
1. can be done with return (read perldoc -f return)
2. can sort of be done*, you can exit a script with exit() (see
perldoc -f exit), die (see perldoc -f die), or croak (see perldoc
Carp).
* At the end of script any END {} blocks that have been defined will
execute (in reverse order of definition). So far as I know there is
no way to skip the execution of END {} blocks, so you cannot end the
script without *any* further execution.
`kill -9 $$` halts the script without executing of the END{}, if SIGKILL
has not been trapped.
Cheers.
