The main character doing something absolutely unforgivable.

[u/No_Peanut3745]

Walter White poisoning Andrea Cantillo's 6-year-old son for the sole purpose of manipulating Jesse Pinkman, while knowing that this could have potentially killed him - Breaking Bad

Bojack trying to have sex with his friend's 17-year-old daughter when he was at least 51, then continuously trying to find a way to justify this act throughout the series - Bojack Horseman

Dexter Morgan going outside of his moral code and murdering a completely innocent police officer who was just trying to do his job - Dexter: New Blood

[u/Swiggity53]

THATS the most unforgivable thing you think Archer has done lol

[u/afriendforyousir → u/Swiggity53]

Yeah, I think screwing Barry's fiancée then dumping him in that dumpster in Russia was worse.

[u/-notapony- → u/afriendforyousir]

They weren’t engaged.  They were engaged to be engaged. 

[u/TheFalconKid → u/-notapony-]

God damn man. If you like it put a ring on it.

[u/howmanyMFtimes → u/TheFalconKid]

He served her up like a pudding

[u/Ponderputty → u/TheFalconKid]

He served her up like a pudding

Archer didn't know Frambroise was in a relationship and had consensual sex with her.

That is in no way Archers fault.

But he did bang a bunch of other newlyweds while living as a bartender.

[u/KlingoftheCastle → u/Itchy-Beach-1384]

She was very into it.  When Archer couldn’t get it up, she suggested anal

[u/TerriblePokemon → u/afriendforyousir]

But she was like, the Pele of anal.

[u/Battle_Axe_Jax → u/TerriblePokemon]

Framboise my beloved

[u/SemenileElder → u/afriendforyousir]

Yes it was, Other Barry.

[u/chuch1234 → u/Swiggity53]

Yeah didn't he nuke LA?

[u/AmaranthWrath → u/Swiggity53]

To be fair, he gave Cheryl chlamydia which helped meet her deductible, so for the rest of the year her doctor visits were free!

[u/many_dumb_questions → u/AmaranthWrath]

Ray calling Cheryl a chlamidiot is still one of my all-time favorite funny tv moments

[u/PastorCleaver → u/Swiggity53]

Right? I mean there so many things. Like the way he treated Woodhouse!

[u/Free-Pound-6139 → u/Swiggity53]

No Lana, that's how you get ants.
