Isn't it weird how 'Imagine' and 'How Do You Sleep?' are on the same album?

So weird cause Imagine by John Lennon is like, supposed to be an inspirational song about loving each other and having peace and then in How Do You Sleep? he's slamming Paul McCartney BIG TIME and clearly all pissed which is harsh especially considering how close they used to be. Kinda ironic and sad how these are on the same album, eh?
