A is for anti, B is for bios

If A is for anti, and B is for bios meaning life, what is an anti-biotic.

If this is going to be against life , why is it being administered to a living person,or if it was only for the bacteria , which is living, should this general term be used, when we could have just adopted anti- bacterial.

Or was it purposely selected to destroy life later on.\

Well if we agree they are termed right, it may have a sinister outcome to be realized at later times.
