Rav Avigdor Miller on Cursing the Wicked 

We say “zichrono li’vracha”  or “zeicher tzadik li’vrocho” for a tzadik. Why don’t we say on a rasha “shem risha’im yirkav” – the name of the resha’im should rot?

Certainly you should say it. And if you don’t say it you’re a liberal. If it’s a real rasha, certainly you say it. You can say “yemach shemo”. And if he’s still alive you can give him a bracha and say “afrah li’pumei” – “May dirt enter his mouth.” We’re wishing upon him that dirt should come into his mouth, in the grave, as soon as possible. Why not? It’s a mitzvah! Shem resha’im yirkav! The name of the rasha should rot away! We are not ashamed to stand up for our principles.

The word “hate” is despised by the New York Times, by the liberals. But certainly it’s a mitzvah to hate resha’im. Don’t they hate the good Jews?! They hate religious Jews. Certainly they do. And therefore we have a right, and it’s our duty, to show that we are opposed to resha’im, and to show that we know that Hashem hates the resha’im. No question about it. In the Tanach it teaches us again and again the foundation principle that ואהב את יעקב ואת עשיו שנאתי (Malachi 1:2). Hashem said that! He said, “I love Yaakov and I hate Eisav.” So what’s the question? And therefore, if you’re speaking about a rasha and you want to add a postscript such as “afrah li’pumei”, I’ll say תבוא עליכם ברכה – you should be blessed for saying that. Don’t be ashamed.
