While we didn't exactly see how Thorfinn become a Slave, i think the farmland arc did an amazing job for his character development enough. Also Thorfinn's change didn't suddenly occur on a time skip. Remember than when the farmland arc started, Thorfinn is broken, he lacks the hygiene even for that time and can even barely speak to Einar. We see he gradually changes from his struggles with at the time he is working for Ketil's farm and one of his major arc for his change is when he see a vision of Askeladd and the arc with the Slave girl that Einar loved.

I will say as someone versed in Icelandic and early Medieval history, his hardcore pacifistic personality is highly irregular for the society and psychology of the time in regards to someone of his status in society. Rather, it seems the mangaka is forcing hardcore Japanese Bushido on a character in the turbulent 11th century Europe (which has VERY different moral codes and beliefs compared to 16th-17th century Japan)
You couldn't be even more right. I'm glad i'm not the only who noticed that. I made an entire post addressing that point how the manga is actually incorporating many Japanese and bushido ideology. It has something to do how both cultures have different mind sets on exploring different lands.

What I meant is that Farm-arc Thorfinn is a new character, and we got to see that character develop. Not the original Thorfinn. The crucial development is seeing how proud Thorfinn devolved into the state of the demure and meek Farm-arc Thorfinn. We didn't see that. The lazy mangaka used a time-skip instead. The character development is just too extreme, quick, and done too poorly. Thorfinn doesn't just accept pacifism, but adheres to a über-pacifistic lifestyle that is hard to see historically plausible even in Bushido-era Japan.
There is a jarring and major dissonance between the main character, and the setting.
