"I am thinking about, what it can do to oneself."

Translation: Jeg tænker på, hvad det kan gøre ved én.

This sentence would make much more sense in English with 'you' instead of 'oneself'. Anyway I don't think anyone younger than 80 still says oneself!

[ZL321]

I certainly do :P

This makes no sense in English because the "oneself" needs a "one", which doesn't exist here, and in any case "it" is the subject of that clause, so the only thing that could be -self'd would be "itself".

Is "ved én" always used together for "to oneself"?

[londoncallling]

I'm not 100% sure but I think the ved goes with gøre rather than en. So 'gøre ved' means 'do to' and then you could have any object where 'en' is.

[zanebl]

That actually makes sense. Tak.

The English sentence shouldn't have a comma at all - that seems a "Danishism"
