The saviour of the Narn race, the hero of the people, worshipped by his own
people - never before has one person been so popular and well liked by everyone.
But it did not start out that way, when he first came to Babylon 5 he was full of anger and mistrust - especially of the Centauri, he came across as a secretive and devious person
who would use any means necessary in order to get his way - and hurt the Centauri.
He preferred to work behind the scenes and ensure that the job gets done without the act being linked back to him.
He did this for most of the first season and grabbing any chance he had at striking at the Centauri - and the most convenient way to do this was through their ambassador
to Babylon 5, Londo Mollari.
His anger against the Centauri and destroying them would occupy most of his time, so in that way it
fuelled his very existence. He could see nothing more than blood and the destruction of the Centauri
as the single objective to be achieved. It would take more than a year and the fall of his homeworld again to the Centauri to realise that there is more to his life and his people than death and destruction.
It wasn't until the episode "Dust to Dust" that he realised the perilous situation his people was in - their hatred
of each other would lead to the ultimate destruction of both of their races and no one would ever know.
To quote a favourite Kosh saying that sum up their situation - "They are a dying people, we shall let them pass".
He had to put aside his own hatred and begin the long process of reconciliation with the Centauri in order to save his people
from ultimate destruction, but not only that he would have to ask some of them to sacrifice their lives through this cause in order for all of them to be saved.
So from that point forward he would try to guide his people through wisdom rather than through retribution.
The Shadow war also has convinced him that far more could be achieved if everybody co-operated together than if they had all separately done their own thing and trying to fulfil their own agendas. So the experiences he had during his stay at Babylon 5 had changed him greatly - so that by the end of the series he was not quite the same person that first arrived on board Babylon 5.
