I have noticed that is it actually kind of easy to manipulate the ideology trees, so you could end up getting pretty much all of the "perks" from all trees eventually. Like for example you make Malevolent choices until you can make the building that generates malevolent points every turn for you. Then you switch to making Benevolent choices until you get the building that makes those points for you every turn. I mean sure, I like taking advantage of cheezy tactics to crush my enemies just as much as the next guy; but it just seems a little wrong that you can get all of the advantages for being "evil" along with all of the advantages for being "good" at the same time.
I'm sure this has been mentioned and thought of by the devs before. I just want to give a little reminder that it needs fixed
