取り上げる表現は"self-inflicted"です。『ジーニアス英和辞典』第４版（大修館）で調べてみたところ、"inflict"には、「（打撃、損害、苦痛、厄介な人など）を与える、押し付ける、加える」や「苦しめる、悩ませる」などと言う意味があり、"self-inflicted"で「（傷、罰などが）自ら招いた」となります。
つまりここでは、「自分自身を撃った」つまり、「自害した」となります。
LDOCEでは"self-inflicted pain, problems, illnesses etc are those you have caused yourself"と定義されています。(Akim)
