Eh....it depends. For example, in the Indochina game I am currently playing, Siam fell into a civil war which was won by absolutists. I’d say my syndicalist Indochina certainly has the moral high ground compared to them. But in my last Siam game, I reformed into a constitutional monarchy and went down the “A Liberal Siam“ path in the focus tree. My Siam was a peaceful and prosperous place.......until we were invaded by both syndicalist Burma, the Indochinese Union, and the Bharatiya Commune, lead by the totalist leader Bose. While I ultimately won the war due to the Reichspakt intervening, and grinding through Indochina from the far south all the way to Hanoi, it was a tough fight which saw most of northern Siam occupied. The syndicalists and totalists brutally invaded me for no other reason than “gib clay”.At the end of the day, the Entente are the bad guys of the three starting factions. The Reichspakt and Internationale are both good in theory (Pakt: Guard the Balance--maintain stability so that another ruinous war hopefully doesn't happen; Internationale: Break the Chains--remove inequality and discrimination from society), but the Entente's theme (Reclaim the Birthright) is a fundamentally reactionary and anti-egalitarian premise. I can totally see a socdem Germany that transitions to full democracy and gives women the vote and anarchist France that makes no aggressive moves coming to blows because of some incredibly stupid tragic bullshit, but I can't see the Entente becoming democratic and still fighting for the "birthright" of some asshole who was squeezed out of the right vagina.
Essentially, the Reichspakt and Internationale are both good in theory but fully capable of being really evil. The Entente are skewed towards an anti-egalitarian, pro-inequality premise from their very tagline.
