Kadara - Angara Settlers vs Charybdis Exiles [Possible Spoiler]

So, these are the known facts:

* The exiles needed help surviving on Kadara because of the toxic water supply.
* The Angara knew how to filter the water but refused to share the method with the exiles.  They instead chose to turn a profit by selling/bartering to the struggling exiles.
* The exiles begged, pleaded, and eventually tried to observe the filtration system to figure it out for themselves...Angara chased them off.
* The exiles poisoned the Angara water supply, killing them all slowly, and taking the filtration method for themselves.

Anyone else not feel bad for what happened to the Angara?  I feel like they got what was coming to them.  Instead of being greedy, they could have shared the knowledge with the exiles and allowed the exiles to be self-sufficient.  Instead, the Angara made them pay for clean water.

I actually felt a bit bad after the game made me kill the exiles at Charybdis.  However, I find it pretty messed up that the exiles also started using the water to turn a profit, after nearly dying because of the Angara doing the same.
