"Murderers, in general, are people who are consistent, people who are obsessed with one idea and nothing else"
About this Quote
The phrase “obsessed with one idea and nothing else” isn’t just psychological description; it’s a critique of moral tunnel vision. Betti, writing in the shadow of Europe’s authoritarian decades, understood how a society can train itself to admire single-mindedness - loyalty, purity, order, duty - and then act surprised when that admiration produces human wreckage. The killer here is an extreme version of a type modernity rewards: the specialist, the true believer, the person who’s stopped being distracted by competing claims. Consistency becomes an alibi.
As a playwright, Betti also knows how obsession simplifies a character into a dramatic engine. A murderer onstage is terrifying not because he’s unpredictable but because he’s predictable: he will return to the same rationale, the same grievance, the same “necessary” act. That inevitability is what turns violence into fate.
The subtext is a warning about our cultural fetish for conviction. When a person refuses contradiction, refuses complexity, refuses other people’s reality, “one idea” doesn’t stay abstract. It starts asking for proof. In Betti’s universe, murder is not a lapse; it’s the logical conclusion of a life streamlined down to a single thought.
