A self-destructive person, habit, or choice is one that is likely to hurt that same person badly — sometimes to the point of killing them. The harm is aimed inward. Someone may stay in a dangerous pattern, pick fights they cannot win, or throw away the things that keep them safe, even while another part of them knows it is unwise.

A self-destructive person, habit, or choice是一個self-destructive（自我毀滅的）人、習慣、或選擇 is one that is likely to hurt that same person badly指的是很可能會嚴重傷害那個人自己的東西 — sometimes to the point of killing them有時候甚至會到致命的程度。The harm is aimed inward傷害的方向是對內的。Someone may stay in a dangerous pattern, pick fights they cannot win, or throw away the things that keep them safe,一個人可能會一直陷在危險的模式裡、挑起自己贏不了的爭執、或丟掉保護自己的東西 even while another part of them knows it is unwise即使他心裡另一部分也知道這樣做並不明智。

Though actually people also use it more loosely: “That was a self-destructive thing to say in the meeting,” meaning it would hurt your own standing, not that you were in danger of dying. The tidy dictionary points at serious harm to yourself. Real talk slides between that hard sense and “shooting yourself in the foot.” It describes a pattern or an act; it is not a medical label you should stick on a classmate.

Though actually people also use it more loosely:不過實際上人們也會比較鬆散地使用這個字 "That was a self-destructive thing to say in the meeting,"像『That was a self-destructive thing to say in the meeting.』 meaning it would hurt your own standing,意思是這會傷害你自己的立場 not that you were in danger of dying而不是你有生命危險。The tidy dictionary points at serious harm to yourself字典上乾淨俐落的定義指的是對自己的嚴重傷害。Real talk slides between that hard sense and "shooting yourself in the foot."實際的說話方式會在這個嚴肅意思和『shooting yourself in the foot』（搬石頭砸自己的腳）之間滑動 It describes a pattern or an act;它描述的是一種模式或一個行為 it is not a medical label you should stick on a classmate不是你應該貼在同學身上的醫學標籤。
