While Helluva Boss's songs are full of stupid, contradictory, and plain wrong lines, it's this one that really gets me...
Because...it's just not true?
If it were about Blitz, I guess it could work? Blitz is basically selling his pride, dignity, and life to Stolas in order to get the book to the living world. It would be disgusting and cruel, talking about a victim like this and saying he "sold his life" to the person who's abusing him, but in a way, it would be tragically accurate.
But it's used against Stolas...? Why?
Stolas did everything but "sell his life". Before this line, Ozzie talks about how Stolas "had a smoking wife, a daughter too". But he still does? And even if Stolas "lost" Octavia and Stella like Ozzie said, he clearly doesn't care.
During Loo Loo Land Stolas neglects his daughter, not giving a damn whether she's happy, just using the day as an excuse of sexually harass Blitz. He only comes to realize his wrongs when Octavia literally runs away to cry about how she feels like her father doesn't love her. He makes a half-assed apology that Octavia has to accept, and all is well! Except it's not, because in Season 2, this happens AGAIN.
Octavia once again runs from her home and her father, this time because he was too busy getting a hate boner while arguing with Stella to give a shit about spending time with his daughter. He doesn't even apologize this time! Loona comes up to Octavia and gabs to her about how she should give her father a pass because he's just a poor, rich, abuser who doesn't know any better and is "trying his best".
Even more confusing, why should Stolas care about "losing" Stella? He hates her, she hates him. They can't stand each other and want to be rid of one another as quick as possible, so shouldn't Stolas "losing" Stella be the best thing that's ever happened him?
Not to mention, Stella acted abusively towards Stolas. Whether you agree with that choice for her character, she still yells at and throws things at Stolas. What would he "lose" from cutting off an abuser like her? If anything, he would thrive even more than he does if he didn't have Stella breathing down his neck like she does. Besides, if he divorces her, he keeps most of the important stuff (money, power, etc.) so even if he did "care" for her he's still well off without her.
And that leads to my biggest point: even if he loses Stella and Octavia, HE DID NOT "SELL HIS LIFE". NOT. EVEN. CLOSE.
He's still rich and powerful, plus he has powerful friends/connections. He can still have whoever he wants. He can still command others through either manipulation, force, or magic. He can still abuse those he deems lower than him.
Stolas can do whatever he wants. Stolas didn't sell his life for shit.
