When evil is being done, is it right to react with evil?

NO! NO! and absolutely NO!!! You should not react with evil, because if you sit there and React with evil when evil is being done, then you are worse than the person who started the evil passing. Although if I was put in some situations then I’m pretty sure that I will not react with evil. If you react with evil then everything will end in tears, but if you don’t react with evil then everything will be hunky dory
