In the novel "Devil May Cry" by Sherrilyn Kenyon, the character Acheron reflects on the pain of giving someone a taste of happiness only to take it away, likening it to showing them the sun and then forcing them into darkness. This quote emphasizes the cruelty of enticing someone with joy and then denying them access to it, highlighting the emotional turmoil such actions can cause. Additionally, Acheron notes that even the devil experiences sorrow in isolation, suggesting that loneliness can be a profound source of pain, regardless of one's circumstances or previous actions. This notion underscores the universal need for connection and the impact of solitude on the human spirit, even for those seemingly unworthy of sympathy.
