hero dilemma

It's hard to fight murder because 
you're out there on the streets 
trying to fight murder, but 
it's not murder unless they 
kill someone.

Then you totally lose. But 
if you win, all you did really 
was fight attempted murder. 

Which is kind of lame.
How 
do you know
they were really going

to do it? 

Were they trying to? 

Is it moral relativism 
or situation ethics

that's the real problem
