would/should
 

Aoa,

1. I wish he [B]would [/B]stop complaining.

2.I wish he [B]should[/B] stop complaining.

I want to know that after the word "wish" which word I should use between "[B]would"/"should".[/B]

3. I agreed that I [B]would[/B] go.

4.I agreed that I [B]should[/B] go.

Which is correct between (3) and (4)?

I think should is appropriate!
