How many sklansky years for your morals?

[Allinlife]

I'm pretty into law dramas like the practice/ boston legal. and often in the show the lawyer would recommend that they take the deal but the client would stubbornly decline saying they can't go against their morals/integrity. Obviously the deal they offer is something like this:

if you take the deal it's 2 years, if you take it to the juries it's approximately 90% you get 5 years and 10% you go free. 5 x 90% =4.5 years, 4.5-2= 2.5 so that's 2.5 sklansky years you'd have to pay for your sense of integrity/morality.

obv in the show they defy the odds and chalk it to variance but I was wondering what I'd do in similar situation. I think I'll take the deal if it is significantly +EV (ie: 5 years+) but not too sure if that's the right thing to do at all. so how about you guys?
