The kanji 慨 is a phono-semantic compound (形声文字, keisei moji). The left side is the radical 忄(りっしんべん, risshinben), which represents "heart" or "emotion." The right side is 既 (ki), which indicates both sound and meaning, in this case, a state of "already" or "having been." The combination suggests a feeling that has already come about or that is a reaction to something that has already happened, linking it to feelings of regret or indignation.
