Sue. Everybody (SPOILERS!)
I find it unrealistic for Lucas to stay in that village after all that happened. And hug the cretin (Johan?) who beat the heck out of his kid, Marcus. Or carry Klara in his arms again (WTF, are you kidding me? I wouldn't have gone anywhere near that creature again, much less without ...recording everything or have 10 witnesses present). Or face that butcher in the grocery store again. They kill your dog, beat your kid, take your job away, beat you up and one year later you share laughs and kisses with everybody at parties? No, dude, just...no. You sell your house, lawyer up and sue the heck out of the entire village starting with that cow, Grethe, and then Johan, the butcher, Klara's folks. Everybody! (almost quoting Gary Oldman in "The Professional"). You create a precedent. You make so much *beep* noise that they'll name your trial in law books.
I vaguely remember a newspaper article with the case of a man who didn't get involved enough in rescuing a child from some accident he was just witnessing because he was afraid of the possibility of later being accused of child molestation. If I remember right, he called 911, but that was about it. He later was sued for not doing more, but he managed to avoid any prosecution. It's a sad state of affairs. But...everything has consequences. Including how society judges individuals.
