killing 1 to save 5?

Would you kill 1 to save 5?
Assume there are 2 railroads, five workers are working on line 1 and one worker is working on line 2.
suddenly a train ()()()() appears on line 1, This train definitely will kill 5 workers on line 1. You are watching this in a control room, you can direct the train to line 2 by pushing a button.
pushing the button means killing the worker on line 2 and saving 5 workers on line 1.
What would you do?

line1 =()()()()======1=2=3=4=5====
....................\\................................
line2 ===============1========


Nowadays scientists are simulating the process of making these kind of decisions on computers.(actually different versions of this question)
It looks interesting. Doesn't it?
I will post more about these simulations later.

The McGurk Effect

Interesting! Brain change sounds to what he/she likes(eyes have seen). it is called McGurk effect:
