Did Sam Rothstein really need to beat up Lester Diamond right in front of Ginger?
Seriously though, did he really have to do it, and did he OBVIOUSLY and HONESTLY expect some kind of understanding and forgiveness from her for doing that to him, as opposed to what happened later, given how she clearly stated to him that Lester Diamond is her childhood friend that means a lot to her?
And also, let's say he DIDN'T beat him up like that and got him hurt and whatnot, do you think that their marriage would've turned out differently and better?
