One of the worst things that a person can do is to hurt someone for absolutely no reason at all. A random attack upon an innocent person is one of the most hateful things that a person can do.
Terrorist attacks are one example of shedding the blood of innocent people. Killing someone for not having the same spiritual beliefs is not a valid reason to murder. Placing others in fear through terrorist threats for the sole purpose of coercing someone to change their spiritual beliefs is not a valid reason to kill someone else. Killing someone because one has a different cultural background or has a different ethnicity is not a valid reason to murder.
Another example of innocent blood being shed is abortion. There is no reason for aborting an embryo or a fetus that has done nothing wrong to anyone. Shunning responsibility of raising a child is not a valid reason for aborting a child. Avoiding the consequences of unprotected sex is not a valid reason for aborting a child. Being a selfish person is not a valid reason for aborting a child.
Let me explain what occurs in the spiritual realm when an innocent person is killed. The blood of the innocent person cries out for vengeance until the murderer dies as well. This spiritual concept is known as the boomerang effect.

The boomerang effect can work in both ways. If a person does something wrong towards another person, then that person will eventually experience some consequences down the road. If a person does something good for someone else, that that person will eventually experience goodness in the future.
Let’s look at a historical example as to how this boomerang effect works when innocent blood is shed. Towards the end of the Egyptian Empire, the first world power upon this earth, Pharaoh Ramses II gave a decree to kill every Israelite child under the age of 2 (Book of Exodus, circa 13th century BC). As a result, the firstborn of Egypt died in a plague. Plus, the entire Egyptian army were killed as well.
Be careful of how you treat others so that the boomerang effect does not mow you down with consequences.
