能不能帮我解释一下一句话的语法?
a man who kills time for no resason is always troubled by feelings of sorryness later

最近在看国外电影(也就想提高一下自己的听力,我听力太差了),里面有句话,我实在理解不通啊! Don't take you eyes off of the wall. 视线别

a man who ,在这里who引导下面的定语从句

who kills time for no reason 是a man 的定语 ,修饰A man ,主干句是
a man is always troubled by feelings of sorryness later. 主语是 a man ,谓语是is 宾语是 is后面的
