What are chemical weapons and what are they supposed to be used for?

Chemical weapons or rather chemical agents have been used since World War1 to injure, demoralize and kill individuals considered to be an opposition force, rebel or enemies in times or war. They have also been used by radical terrorist seeking to make a social or political statement.

 In the YouTube video Truthloader channel talks about what chemical weapons are and what legitimate purposes they are sussposed to be used for such as preventing"the multiplication of cells, or as fumigants, herbicides or insecticides" according to Organisation for the Prohibition of Chemical Weapons.

 Although chemical weapons can be used for positive purposes throughout history these agents have been used to destroy like and eradicate thousands of people. Just like cocaine, chemical weapons were not considered to be socially destructive or even dangerous a few decades ago.

However humans began to use chemical weapons irresponsibly and for their own selfish reasons.

 Leaders of countries and radical groups desperately seeking to obtain control and demonstrate that they have power has relied of chemical weapons in the same manner that coke heads rely on cocaine.

The more frequently these weapons are used for evil the more corrupt our world is gradually becoming. It seems that now whenever a leader or radical group wants to fend off their enemies or silence their critics they rely on chemical weapons to do the job for them instead of simply having face to face discussions,debates or making compromises with each other.

 I don't believe God intended for humankind to settle their disputes with poisoning each other and causing massive human suffering just to say they were the last one to have the last word in an argument. But somehow our society has grown to believe that they must used chemical weapons as their new boxing gloves as they are lethal fighting each other in a boxing ring until they both sides are completely knocked out.
