Is Xがないとだめ "must have X"? And sentence-ending かね


In an anime, two characters are talking about playing basketball and why
should someone not versed in it be interested at all; one of them says:

> バスケやるのに理由がないとだめですかね

which is translated as "To be honest, I'm not sure anybody actually needs a
reason to play basketball". I'm not sure if I understand the sentence, but I
think in the translation there is something different from the original (like
it being a question turned affirmation, if I'm right).

My breakdown is:

  * バスケやるのに: in order to play basket
  * 理由: reason
  * がないとだめ: が particle + must have
  * ですかね: です + question marker + ね particle

More literally, it's something like "Do you (really) must have a reason in
order to play basket?", so "Do you really need a reason to play basket?"?




> 「バスケやるのに理由{りゆう}がないとだめです **かね** 」

Translator's TL:

> "To be honest, I'm not sure anybody actually needs a reason to play
> basketball."

Your TL:

> "Do you really need a reason to play basket?"

Both look "okay".

To me as a native speaker, however, the nuance of the sentence-ender 「かね」 is
considerably more important for a deeper comprehension of this sentence than
the meaning of 「Xがないとだめ」 because 「Xがないとだめ」 only has one simple meaning with no
hidden nuance -- " ** _if there is no X, it is no good_** ".

「かね」 makes the sentence a mixture of statement and question. It implicitly
asks for the listener's opinion (or at least a reaction) while making a
statement with a hint of uncertainty held by the speaker regarding the content
of the sentence prior to the final 「かね」.

In other words, it is not easy translating sentences ending with 「かね」. One
would need to "borrow" some words that are not used in the original sentence.

My own TL:

> "I wonder if you actually have got to have a reason to play basketball.
> Whatcha think?"
