I would have to say...
None.
To keep the sanity in check of the capsuleer.
It would have to be none.
All the 'people' are nothing more than ants.
The thing with the Amarrian mentality is that if they are not ants, they are martyrs.
Which would mean that on emotional level they would be nothing more than ants.
The heathens that die, they are subhuman, even less than ants.
But if you want to rub your epeen, sure, Lall had about 20 active BSs, a cap, a few industrial ships, about a hundred cruisers, almost a thousand frigates around... I guess that would sum up to around 200k people involved in her combat operations.
But still, they would mean about as much as ants.
If I would like to wank some about her background and her family... you could add a few hundred to it.
But they could mean nothing anymore, mainly because of her perception of Godflesh.
If you would like to take into account all the people that were employed in the service of the capsuleer entity that she is, during her whole career, you could tag a few million, when you take into account all the production personnel, research personnel, recycling personnel, personnel connected to the missions and all the people that had died in the combat operations that she had been part of (friend and foe). But most of them overlap with the other capsuleers, mainly because they are part of the infrastructure that upkeeps them and makes them feel oh so special.
In the end when the push comes to shove, I would have to say that it is the whole Holy Amarrian Empire that has supported her as a capsuleer. To make her one and to keep her as one.
It is pretty much about infrastructure.
Which is really hard to limit.
(When she was a newbie she mined in the Federation and sold the minerals there, which would mean that the whole Federation was supporting her antics.)
