21. Maximum Security Prison Guards
Every working moment for a maximum security prison guard is an ultimate exposure to dangerous and ruthless criminals. This job involves guarding serious offenders and controlling the most violent elements of the world’s murderers, serial killers, rapists and the most hardcore gang members who actually have nothing to lose and little regard to human life.
These criminals not only hate prison guards for who they are, but more so for what they represent. Showing mercy to these criminals wouldn’t change anything because they will only see the prison guard as being weak and wouldn’t reciprocate the same. On the other hand, showing no mercy would even be worse because they’ll wait for their opportunity to strike back, even though such an opportunity might never come. But if it ever does, the prison guard would be no more and probably in the worst possible manner.
