Inventions I wish had not been invented

This is very difficult to narrow down. So much of technology is extremely beneficial, if put to proper use, yet can be detrimental in the wrong hands. Even things which seem all good can be turned to bad in the mind that leans in that direction. One glaring example is the H-bomb. It is the epitome of evil. However, the technology to create the bomb is also the ability to create massive amounts of energy relatively cheaply. Dynamite is another example. It can be used as a quicker, more effective mining devise than picks, axes and shovels. But, in the hands of people with destructive minds it is a tool for great harm. I would much rather allow for all creativity to be permitted to flourish. God gives us free-will and I believe we should, in turn, allow our fellow man to have the same freedom. This means we will be infringed upon, yet we will be allowed to infringe upon others. Stifling each other is not an effective tool, rather compromise is called for. Compromise and being an example of responsible creators and thinkers.
