Born in Lithuania in 1906, Levinas studied as a young man with Edmund Husserl and Martin Heidegger and later developed a philosophy of his own that holds as its core principle the "infinite responsibility for the Other."Certainly Heidegger was immoral, but I don't see how the same can be said about the interesting bits of his philosophy in a meaningful way. Ontology is disinterested in morality.
After Heidegger joined the Nazi party in 1933, Levinas began what Gordon called "a laborious process of distancing his own philosophy from Heidegger's." He eventually came to regard his teacher's philosophy as "suffering from a kind of moral autism," Gordon said.
