Why not observe first and then act instead of act first and deal with the consequences?

Staying here to see if the guards in the front do anything is an action too, and it can have consequences. It could be quite inconvenient for us to stick around until the guards discover that the patrol is no longer patrolling, since they might start searching the area or telling other guards.

Getting rid of the guards in the front would leave us with no-one who can discover our murders. If we can do it, it'd be safer.
