I don't quite see why I should be responsible for what happens after I've made a decision, unless I have some kind of telekinetic powers. A decision is something abstract and isn't necessarily followed by an action. On the other hand I can be concerned or worried as to how what I've decided to do will affect my life or other people's IF and WHEN I do it. At least that’s how I see it. I’d appreciate your explaining why you chose the first option here.

Hi Conchita,

I accept your logical comments but really this is a language thing. Concern is usually used in a negative way as in:
It's not my concern/no concern of mine what happens.

Again in both negative and positive statements using the same basic form:

I'm not concerned about/I am concerned about what happens.

The most appropriate word here is responsibility however unfair and unjust you may think the comment by the speaker may be in making the other person responsible for what happens.
That's why I chose that word.

Hello Alan,

Thank you for trying to enlighten me, which you are usually very good at. From now on, I'll think twice before airily saying that English is not that complicated.

Hi,

I was really being carried away by your conversations here and almost forgot my question....

So, be down to you = be up to you = be your responsibility. To me, this is another example for the 'up = down' phenomenon as we have in: fill out = fill in (out = in ), live off = live on (off = on ), etc. Oh, sorry for my rubbish but I just wondered if there had been something behind the scenes to actuate these phrases to be equal or close in meanings but with opposite 'parts'.
