So?Yes it is. But we've already been over this.Whether you like that turn or not, it's not a plot hole.
No it isn't. The character explains his actions right there in the scene.
From Wiki (emphasis mine):
A plot hole, or plothole, a play on the word "pothole," is a gap or inconsistency in a storyline that goes against the flow of logic established by the story's plot, or constitutes a blatant omission of relevant information regarding the plot sometimes even contradicting itself. These include such things as unlikely behaviour or actions of characters, illogical or impossible events, events happening for no apparent reason, or statements/events that contradict earlier events in the storyline.
