This so much. Not sure what the legal boundaries are for a lawyer in the USA, but over here the lawyer has to "defend his clients interests". A lawyer has no obligation to to refuse a case because it is pure horseshit. If you are paying him because you want to go to trial, he will do so because you are paying him. At some point he should mention "well it is unlikely we will win" but after that, if you insist and you keep paying, the lawyer will keep going.
