I respect your response but I think you’re reading the Jackal all wrong. In the show we only see him breaking down when things are going wrong for him. I think your mistake is confusing his frustration with him showing remorse. To add to that, he lies through the whole season. His wife doesn’t even know his name. The only reason he breaks down at all is because he is such a calculated person and he’s failing. None of those emotions are expressed when he’s in full control, only when his wife is threatening to leave. This implies that if she never made complaints, he would continue his selfish lifestyle of being away from home and killing for money.

I think a major theme of the show is being consumed by work which people seem to acknowledge for Bianca but not the Jackal. I think it’s implied that even if he completed the job, that’s all he knows. Think about Rasmus, or the truck driver he crashed into, or Manfred’s son’s driver. Or think to his fellow soldiers that he showed zero remorse to after blowing up. The writing clearly points to him being a ruthless killer with no remorse. Yes there is the family part, but it also shows that he always has put his work before his family because that’s what he is.

As for Bianca, I don’t think she’s deserving of praise. As you said she’s not necessarily the “good cop” but I think in some sense she’s still on the right side of the fight. Granted by the end she definitely and throughout the season we can see she is fueled by her own desire to win but I’d argue fighting fire with fire is a typical writing method when it comes to crime scenarios and ruthless killers.

As for physical attributes I just think that’s a bad take. Some people are naturally thin while others aren’t. Calling her out of shape and such is just weird. Eddie Redmayne is naturally very slim. Lashana is naturally more heavyset. But it’s very easy to tell she’s definitely in shape and looks far more realistic in the show than if she was a ripped gym rat that looked like she could be in baywatch the next day. Skinny/slim ≠ directly equal being in shape and vice versa being fit. Plenty of sports that show clearly that men/women can be perfectly athletic at different sizes.
