Antagonist in Mourning/Playing With

Basic Trope: A villain mourns over a hero's death.
 * Straight: Evil Bob kills Steve, then goes to the funeral
 * Exaggerated: Bob, having finally killed his nemesis, Steve, is so grief-stricken due to his loss, that he decides to give up his life of evil, perhaps even turning good himself.
 * Justified: Bob has focused his life around his nemesis, Steve, for so long, that he must seriously consider what to do with his life with Steve gone.
 * Inverted:
 * Bob couldn't care less about that fool, Steve, who thought to oppose him. When he finds that Steve is actually alive, he falls into a deep depression.
 * Alas, Poor Villain, but in-universe.
 * And There Was Much Rejoicing
 * Subverted: For a moment, Bob gives a thousand yard stare, but otherwise appears unaffected by Steve's death.
 * Double Subverted: Later that night, we see Bob crying himself to sleep in his room.
 * Parodied: Bob had a Foe Yay crush on Steve and tearfully admits it to the rest of his party...much to his humiliation.
 * Deconstructed: Bob is a Punch Clock Villain who secretly respects Steve. However, he can't join Steve's side because the Big Bad is holding Bob's family hostage.
 * Reconstructed: Over time he grows to hate Steve, but maintains respect for him, and is upset when he is killed.
 * Zig Zagged: Bob goes to Steve's funeral, only to whip out a gun and shoot Steve's True Companions at the funeral. Then he bursts out in genuine tears for Steve.
 * Averted: Bob couldn't care less about that fool, Steve, who thought to oppose him.
 * Enforced: Let's show how nice a person Steve was by having Bob mourn for him.
 * Lampshaded:"You know, seeing as he was your arch-nemesis, I’m really surprised how cut up you are about this."
 * Invoked: Steve is killed by someone other than Bob specifically to upset or insult Bob.
 * Exploited: Steve fakes his own death in order to render Bob hopelessly depressed and unable to carry out his plan.
 * Defied: "Quick, Bob! Kill Steve!"
 * Discussed: Before killing Steve, Bob talks about how he may just be upset when Steve is dead. Musings about a thin line between love and hate may be said.
 * Conversed: "Ooh, the battle between Steve and Bob looks bad." "I hope Steve wins. Bob's a horrible wreck at funerals."
 * Played for Laughs: "Uhh...I'm Not Quite Dead" "OH THANK GOD!" *Glomp!* " I don't know what I would do without you!
 * Played for Drama: Bob can't adjust to Steve being dead to the point he either commits suicide or is eventually cut down by another evil rival.
