This words means "The act of killing someone painlessly (especially someone suffering from an incurable illness)"... also called "mercy killing".
Today morning in the bus I was reading "Doctors" novel. There it talks about mercy killing.... A doctor Seth, kills his brother Howie as he was suffering from brain damage.
How I wish it wasnt just about illness or something... it would be good if one kill oneself if they doesnt want to live anymore... many people suffer from depression and stress... they should make a law that a person can go ahead and do such thing...
and for terrorists and criminals and corrupted politicians... killing them should be mandatory instead of giving imprisonment for 5-7 years.
