Sometimes the pain is so excruciating/unbearable that people choose to die instead of living. Death seems to be the only easy solace. What those people do is wrong, but probably they are not in a state to differentiate between right and wrong. But, people who choose to live and fight, die every second thinking every moment to literally die, but can’t because of the responsibilities they have to take care of. In both the scenarios one’s are anyway dead, one in literal terms and the other mentally,spiritually,emotionally. The former takes the pain with them and the latter just augments the pain every second if he fails to fight.
