(SPOILERS) -- Hard to feel sorry for... -- (SPOILERS)
...the "victims" of the poker scam, because:
1. Most of them had defrauded others in their daily business dealings
2. The entire lot of them, all throughout the movie, circled around their "prey" (Henry Fonda, who, in reality, was the "predator") like a flock of vultures, thanks to the bit of "misinformation" they'd been given about his being a failed ex-gambler -- so, for once, they were being given a taste of their own medicine
3. None of them were ruined by losing out to the wife of the supposedly indisposed Fonda (Joanne Woodward) and some of them actually came out better men for the experience (Charles Bickford and especially Jason Robards!)
4. Technically, Fonda & "wifey" didn't cheat! The hand was won on a bluff (though the con artistry among them, the banker and the doctor is undeniable)
Okay folks, show's over, nothing to see here!
