Power Book III: Raising Kanan concludes by resolving the season-four cliffhanger about whether protagonist Kanan killed his mother Raq. The series reveals he struck his uncle Lou-Lou instead, and throughout the fifth season, Kanan remains determined to sever ties with Raq, even tacitly endorsing assassination attempts against her by associates and rivals. In the finale's climactic moments, Kanan unexpectedly undergoes a change of heart, negotiating with crime figure Stefano to spare Raq's life whilst also confessing to killing her brother Marvin and seeking maternal forgiveness.

Raq's death ultimately comes not from Kanan but from his cousin Jukebox, who witnesses their emotional reunion at a shopping centre. Jukebox deliberately chooses to kill Raq as a form of revenge for Kanan killing her father Marvin, calculating that this approach will inflict prolonged psychological torment—condemning Kanan to lifelong isolation and loss—rather than simply ending him. The series conclusion, titled "Unconditional Love" and drawing on real events from creator Curtis Jackson's autobiography, uses this tragic reversal to illustrate how revenge and violence spiral through family relationships across generations.
