Greed

One potato, one knife, two very hungry friends.
 -Would you pick up the knife... Cut the potato in half?
 -Would you pick up the knife.... Cut his throat, so you can have it all to yourself?

The plane is about to crash, it is just you and her, one parachute. She does not know how to operate it. 
 -Would you pick the chute up... teach her how to use it, and give it to her?
 -Would you pick the chute up.... strap it on, and jump out before she can move?

You like a girl, your friend likes her too, she confesses her love for him to you.
 -Would you ignore the fact that he likes her, would you tell bad lies about him?
 -Would you tell her the truth, hold back your love for her, so your friend can be happy?

Think about it, honestly.
