I need suggestions for different ways to say "turning criminal," as in "He began turning criminal, committing illegal acts instead of abiding by the law."
If you're going for subtlety, try
He began to cross the line, committing illegal acts instead of upholding the law...
Other phrases you could substitute here for the bold text would be:
- turn to crime
- cross over
- cross into the dark side (pop culture reference)
Edit: if the character was also homosexual you could make a double entendre with the phrase batting for the other team
Edit2: triple entendre if he was into baseball.
4. not straightforward; dishonest.
Almost always meant in a criminal way. (i.e. a crook.)
