Point being that cooperation in a prisoners dilemma sense means choosing the strategy that would maximize my expected payout if everyone chose it, and in this game that is not equivalent to cooperating with probability 1. If it was supposed to measure strategies, the question would have been better if it asked us for a cooperating probability and then Yvain would have had to draw the numbers for us.
I think accidentally choosing defect is probably the best possible outcome in PD; you get all the advantages of defecting, whilst your decision process still acausally causes other people to cooperate.
I threw a D30, came up with 20 and cooperated.

This was based on a math error, it actually is a prisoners dilemma.
I made a similar mistake, and randomly generated defect.
Welp.

It can get even better, assuming you put your moral reasoning aside.
What you could do, is to deliberately defect and then publicly announce to everyone that it was a result of random chance.
If you are concerned about lying to others, then I concur, that accdientally choosing to defect is best of both worlds.
In the literal PD scenario, I imagine the subsequent converation would go:
“You accidentally informed on us? Okay, we’ll accidentally shoot your legs off.”
