"And why would it have been a problem too? I can't imagine a bunch of people being a problem for us though." I was confused by the fact that how could some humans or normal statuses probably, would be a problem for the people who just dealt with the Wretcher itself.
*The answer to such a form of confusion can be answered by asking another question of the same type or kind. Ask yourself this, would you or would you not, have trouble hurting or killing turned or infected humans who could possibly be cured later on if dealt safely rather than break their bones without any show of mercy towards them whatsoever.*
