Should you drain the fat from beef for chili?

I cooked chili the other day with 93% lean ground beef, added a can of water, and used the fat + water as a sort of broth in my chili. It turned out fantastic, and the directions my mom sent me didn’t say whether I should drain the fat from the ground beef.

While talking to her on the phone she said I should have drained it. Maybe we use different types of beef, but I was under the impression 93% lean seemed healthy enough to keep the fat.

My first question is health related: is it unhealthy/ unwise to keep the fat when you’re using the leanest ground beef you can find (93 or 95%). Secondly, which do you think is better, drained beef in chili or undrained?
