斯维里加洛夫的“罪与罚”是陀思妥耶夫斯基《罪与罚》中的支线情节。斯维里加洛夫是一个作恶多端的道德堕落者，他彻底摆脱了内心的罪感之罚，最终却因为无法恢复这种道德情感层面的“罚”而绝望自杀。他“忧郁”的生存体验是他死亡的逻辑起点。他的忧郁代替罪感起到了“罚”的作用，兼具毁灭性和拯救性，既是他走向自我毁灭的前提，也是促使他寻求自我拯救的精神因素。实现道德自新是其自我拯救的核心内容，自我拯救的失败导致他走向了自杀。小说主要通过他和杜尼亚的互动以及他自杀前夜的梦境来表现他自我拯救的意识和行动。他悲剧命运所表现出的深刻矛盾性，可以从他对生之意义的追问态度及其死亡的象征意义这两个方面来理解。

Svidrigaylov in Dostoevsky's "Crime and Punishment" is a subplot character who embodies moral degradation. He completely sheds any sense of guilt, yet ultimately despairs and commits suicide due to the inability to restore the moral "punishment" on an emotional level. His existential anguish serves as the logical starting point for his demise. Instead of guilt, his existential anguish functions as a form of "punishment," both destructive and redemptive, leading to his self-destruction while also driving him to seek salvation. The core of his self-redemption lies in moral renewal, but his failure in this endeavor leads him to suicide. The novel primarily illustrates his awareness and actions toward self-redemption through his interactions with Dunya and his dreams on the eve of his suicide. The profound contradictions in his tragic fate can be understood through his questioning of the meaning of life and the symbolic significance of his death.
