The idea of <em>running away </em>is actually implied in the sentence, as '<em>fuge</em>' is the root word of 'flee' (it composes words like 'subterfuge' and 'refuge').
So the most approximate meaning os the sentence would be:
To me it sounds like both 1 and 3. As I don't think it could be 2 as running is mentioned no where, and not 4 because no where in the sentence is the future mentioned.
if they take pride in their reputation they dont wanna get caught cheating because it will ruin their reputation so it is very unlikely they will cheat
