Ariel Castro took the "p**sy" way out when he decided to hang himself in his prison cell ... so says Tom Arnold who tells TMZ the guy shoulda been strung up by his balls.
Arnold was at LAX today when we asked how he felt about the evil Ohio kidnapper, rapist, scumbag taking his own life this week.
"If his victims are fine with it, then I'm fine with it," Arnold said ... "but it's the p**sy way out."
Arnold says the country needs to focus on supporting Castro's victims -- but says, "If I know women, they'd want him hung by his balls."
