Overall, yeah, sort of. There are exceptions though. In a recent game as China, everyone was playing the I love everyone and lets be friends game except Babylon. Babylon was a grinch that hated the world and wanted to destroy it. When they threatened to take the Netherlands' capital, I declared war on them, beat back their army, and took one of their cities in a peace deal. Then, nobody feared Babylon for the rest of the game, and rarely a turn passed when at least 2 civs weren't at war with Babylon, trading turns between the Shoshone, Netherlands, Americans, Chinese (me, to protect the Netherlands when they DoWed Babylon and were about to lose their capital, it happened a few times that game), and Ethiopians who sent armies to Babylon, and a few others who declared war but were too far away to do anything. Everyone else in the game were friends.
