Is there a word or name for the phenomenon or syndrome in which people try to defend one wrong thing by comparing it something that is total opposite of it but also wrong?
For example:
Drone attacks are the right thing because they are against terrorism which is wrong.
A more general but abstract kind of example could be:
I want to kill all the sharks because they are dangerous for human beings.
