You should find out what in particular led him to this path.

It is one thing to skip a mincha, or to eat a treif thing because of curiosity.

Here THere may be something bad that happened to him that should be discussed.

Also there can be psychological issues, for example, I myself, hate going to Shule, at times, because I hate the crowds, the whole social aspect. So sometimes I just don’t go.

Not saying this is a good mida, but

you see that reasons for actions are important.

Much luck to you.
