There are many things that are worth dying in life. There can be political, environmental, spiritual, and social issue to fight for. But for me, the spiritual issue is the most important and is worth dying in my life. There are lots of types of spiritual issues, but I strongly suggest for love. I would die for love because love is all the solution for any conflict and people cannot survive without love and also people often give up everything just for love.
First of all, the love is the solution for any major conflicts. Personally, when there is love between people, they seldom get into fights and they deride each other. Even if there are fights going on, they get over with it in very little amount of time.
