When the blood stops flowing from the bleeding heart life ends in a literal and metaphorical sense. A bleeding heart is someone who cares about others out of a sense of human decency and bonds that link humans to each other. Blood pumping out of the heart is not eternal and could get blocked by events orchestrated by outside forces. When those forces are too great, a person is left moribund and surviving on life support in critical condition. This situation is closer to a death by a 1,000 cuts than death by suicide.
Bleed hearts flowing with rich blood gives life to humanity and compassion for even the least amongst us. For various reasons-based on the individual-they work tirelessly to make the world a better place and bring a little sunshine to the darkness of life. People around them may think them naïve, but must respect their commitment to improvement of the lives of those around them. The world is changed, hopefully for the better, by those who care enough to work for change, and not by the apathetic and the pernicious. The world usually does not return the favor which cast a dark cloud upon reality and continued efforts to improve the future.
The problem with having a bleeding heart is that sharks smell blood and will attack at the first opportunity available. They find the blood of the bleeding heart delicious and because of their ravenous nature, their greed will devour as much blood as possible. Drawing from the rich nutrients of the blood, the sharks can feed for a long time because the supply is in abundance. The sharks have shallow, decrepit hearts which makes feasting on fresh blood necessary. The sharks will devour the world and will not stop until the bottomless well of their needs are satisfied.
What society lacks is a sufficient appreciation of the bleeding heart, which serves to prevent new life from forming. Before long, a new generation will become stone cold from an emotional standpoint, which will produce a legion of emotional zombies; fully functional humans who can simulate emotions at best instead of feeling them. Compassion and sincerity will end and be replaced with selfishness and rugged individualism. If this trend persist, a new era will slowly be created in which society will be unrecognizable and worse off than before. This grim trend could be prevented only if people could observe a universal standard of decency and respect.
