>I would have to go. Hanush would approve. What has a nobleman but his word and his honor? But it’s not worth it, Henry. With a bit of luck, someone else will deal with him soon. And you’re not let yourself get killed now that’s everything’s been settled! Look, I’d rather you forget about it and just stay here.Zizka, being more a merc than a noble thinks it’s dumb, but he also notes “if you think he will become a problem for you later, now is your best chance to kill him you’ll get”. And as
>>521592532 said, Henry’s subconscious (dream Istvan and ghost dad) keeps telling him that he will have to pay for Erik’s personal loss with his own eventually.
TL;DR: From Henry’s unique perspective, Erik needs to die as fast as possible. The real question is why Godwin apparently thinks so too.
