I know you're provoking me, but that's exactly what I would do! Call me insane, psychopath or any other medical / criminal term you may want! The only difference is that I wouldn't stop only with him, I'll search for his family members... All of them, until police catches me. 
  
  
  
 
Nope, but don't need to to understand the emotions involved. 
  
I've met you, you're a decent human being, not an utter psychopath. You probably would go mental at them and batter them with whatever you had to hand in the heat of the moment, but that's it. No way would you: 
  
Stalk them for a week to learn their movements 
Hatch a plan to kidnap them 
Find a secluded place to take them to 
Kidnap them 
Tie them up securely 
Keep them conscious 
Pick a selection of tools with which to do nasty things (use your imagination here!) 
Carry out the acts 
Keep the suffering going for as long as possible 
  
  
No chance, because you're not insane. That's a good thing mate, and I don't believe anyone on here would be capable of any of that either, regardless of posturing. Instant anger yes, but calculated revenge? Nope, not buying it,
