Given what happened in Sweden when he was kicked out of the Ecuadorian embassy and the UK arrested him for extradition to the US, I believe the Swedish accusations were made, and the prosecutions were done, in good faith.

Assange's argument against going to Sweden should've logically also applied to the UK, where he physically was while trying to make the argument to avoid extradition to Sweden, as demonstrated by the UK not even bothering to inform the Swedish authorities when they finally did arrest Assange.
