Kristian? Was it because he was insane? Was she repulsed by him? Or was it a mercy killing of sorts?
Great film, by the way.
Can't say for sure. Two thoughts that came to my mind are "revenge" for his father raided her settlement and second is the mentioned "mercy" killing as he's been insane already and basically didn't have a place to go.
"He say you Blade Runner." "Tell him I´m eating."
I think it ties in with the backstory of how her brother, Adam, lost his arm, and with the Kozlik family's gradual transition from paganism to Christianity.
In an early flashback we see Alexandra walking naked through a field, carrying a chicken and a knife for a bloodletting ceremony at the relic-adorned tree where she conducts her pagan rituals. There she has sex with Adam, and a snake crawls down from the tree and bites him on his left arm during the incestuous act. (All kinds of Christian imagery there, eh!) Alexandra tries to suck the poison from the wound but to no avail. Then she conducts her pagan bloodletting ceremony.
Later in the film another flashback picks up story. Adam's mother tells his father that Adam has committed incest with his sister and that "the mark is upon his arm" and "the poison is in his blood" as the result of his sin. The father chops off Adam's infected arm, telling Alexandra that she will stay there to die along with her brother or be spared if he lives, depending on "the gods'... God's will." Kozlik's correcting himself this way indicates he's begun his conversion to Christianity.
What I took from all this is that Alexandra believed she was to blame for Adam losing his arm, and that the punishment (and eventual mercy) were meted out by God. Her rituals to the pagan gods were meaningless to the one true God. So when she takes Kristian to be her lover, outside the bonds of holy matrimony, and he goes insane... she blames herself once again. Thus she lifts a rock and bashes him in the head (where the "poison" resides, like it did in Adam's arm) and waits there with him to receive whatever punishment or mercy God decrees. She's still there with him when Marketa leads Kristian's father and bodyguard to the scene.
Nice view, I could go with this one. After another viewing I would dismiss my previous comment and go more for something like this.
"He say you Blade Runner." "Tell him I´m eating."
One possibility which fits her character.
Alexandria doesn't go in for half-measures- she knows what she wants and goes for it. When her father threatens to hang Kristian she picks up an axe and we know it isn't just the rope she'll use it on.
When they are fleeing Beer's attack on the compound Kristian pauses and allows himself to be captured or returns to his father. As far as Alexandria is concerned that's betrayal and it doesn't matter that he changes his mind later. His insanity, which could be temporary or extreme exhaustion, makes no difference. The fact that Kristian doesn't recognise Alexandria just before she kills him ties in there- all or nothing is her motto. She is captured later when she's performing some kind of pagan rites over him- bringing about his rebirth or destroying his christianity?- indeed, his name is undoubtedly significant to the film's symbolism.
