Absolutely and categorically not.
One is born with a right to freedom, this freedom is, among other things, to make choices.
Choices as in this or that, wendys or burger king, left or right, good or evil, moral or immoral.

Furthermore, immoral is just a point of view. I can do many immoral things (according to my society), which, while taboo, are not neccesarily illegal. I absolutely have the right to do so.
