てか

「貴様に選択権などあると思うてか？四の五の言わずにその穢れを祓うがよい」

Hi. What is this てか? How is it different from just か?
Thank you.

思うて is a classical or dialectal version of 思って. Two interpretations are possible, 思っているのか or 思って（そんなことを）したのか. I don't know the context, but it seems to be the former one to me.

You might already realize this, but the speaker is using a classical wordings that sound solemn and arrogant like samurai, most likely to show their character.

Thank you, Toritoribe-san.
