Did the killer betray himself subconsciously when he missed?

So there he is. Paris.

The target. The dominatrix.

The dominatrix moves and then he pulls the trigger. In that precise order.

We hear The Smiths How Soon is Now?:

"There's a club if you'd like to go
You could meet somebody who really loves you
So you go and you stand on your own
And you leave on your own
And you go home and you cry
And you want to die"

"And you want to die" is heard. The dominatrix moves. Then the killer pulls the trigger and misses. In that precise order. A coincidence?

The song also says:

"You shut your mouth
How can you say
I go about things the wrong way?
I am human and I need to be loved
Just like everybody else does

When you say it's gonna happen now
When exactly do you mean?
See I've already waited too long
And all my hope is gone"

Under this light, and given that the Killer eventually retires, maybe we can ignore his 'there's no fate' and 'the only life path lies behind'. That's what he thinks as a killer, but maybe a glimpse of fate, of the boyfriend-as-a-retired-killer got in the way when the dominatrix moved...from the left - from the sinister side.

Hence his left eye twitch at the end. We are like him, weak, one of the many, and as The Smiths say in How Soon Is Now?:

"You shut your mouth
How can you say
I go about things the wrong way?
I am human and I need to be loved
Just like everybody else does"

How could he miss? How could he go about things the wrong way?

The Expert speaks about the impossibility of another life, but the Killer ends up having another life, as boyfriend or husband. But between two lives there must be a death. Hence the relevance of the lyric 'and you want to die'.
