Is Universalism a Diabolical Attitude?

I almost entirely abandoned Christianity as a young man, what sort of rescued me were arguments that Vladimir Soloviev made in the treatise of God. And I realized that I needed to free myself from certain notions of what was or was not the Orthodox view. But then again, let's be honest, and I try to avoid the sectarian things, but I mean, this is part of the sickness of a kind of one way of understanding Roman Catholicism.
