Battling spoilers!

Spoiler:

It may not have needed to be Bond specifically but it was only through the actions of Bond that any movements towards Silva's confrontation of M was achieved. Plus not only did he have to get captured but he had to get captured at just the right time so that he'd be transported to London, interrogated, have Q infect the network at just the right moment so that he could escape and not just assassinate M but do so while she was testifying before the parliament committee.

Seriously, it was a plan that make Heath Ledger's Joker look feeble minded.

But the part that bothered you doesn't bother me because it was part of the horribly unlikely and convoluted plan. The assassin needed to be separate from everybody else in on it because the assassin was bait for Bond (or whoever else) so that Bond would find the casino chip and follow it to Macau and from there get to Silva. The thing I wonder is if the assassin knew everybody else was in on it.

And one thing has really settled poorly with me over the last date. One horribly wrong emotional note:

Spoiler:

Seriously, as it has settled, I find Bond getting naked and sneaking up on her and groping here without warning, even though he knew her to be a horribly sexually damaged person. One who, so far as he knew, would consider sexual submission to him the cost of seeing Silva killed. Just a horrible scene from the point of view of what the character of Bond believes he knows at that point and what it says about him that he'd act that way.

That isn't sexually promiscuous it is very nearly sexually predatory. Especially when the next day she is killed and he barely bats an eye. Surely he enjoyed his night with an attractive woman who had learned many great skills in her 20 years of forced sexual labor.
