Some times decision taken without profound logic base can be disastrous. Read the following story.
 
Five persons were traveling together. They met each other while on journey. As there was no vehicle available all of them were traveling on their foot and in the process they developed friendship among them.

In middle of the journey, rain started pouring down. All of them took shelter in a temple near by.
 
A lightening (which you see during rain) came out of the sky started revolving around the temple. It frightened all of them.

They thought, "One of us must be sinner, and this lightening is after ending his life."

So, they decided that each one of them should take a round around the temple. If he is sinner, lightening will end his life so that others will be saved.

According to the decision, four of them completed their round and it was turn of the fifth one. He was too afraid to go out. All others compelled him. The moment he went out, lightening entered in the temple and all those four were left dead.

They could not realize that their lives were saved because there was one within them to whom lightening could not have touched!
