I like playing Benevolent, and I like the bonuses. Unfortunately, I have found that I like the bonuses from Malevolent much much more. +10 raw production to your Homeworld and 100% boost to your home world shipyard results in me being able to pop up a colony ship a turn - at 50% military spending. Or you can wait till you fill up your homeworld and send all the manufacturing to build ships, and still have 50% available for research.
Please cut both bonuses by half.
I also think it would make more sense for the Malevolent building to be military, and the Pragmatic one trade / money.
