Looks like you have plenty of other foliage, you can either leave the leaf alone or just pull if off.
Leaving the leaf on may slightly increase your plant's infection risk as the exposed surface is fairly large, but honestly plants are pretty good at preventing that when its only a minor injury. The benefit of this, as mentioned in a comment is that the leaf may still be capable of productive photosynthesis.
Plucking the leaf will leave you with a minimal opening for infection (just the location where the plant is attached to the stem) so that may be the better option.
Honestly I don't think you will do much harm to your plant whether you leave it on or off. Plants lose leaves all the time for a variety of reasons, they also take damage to their leaves for a variety of reasons (bugs, birds, humans, even hail). They are pretty well prepared to deal with them.
What I would do is leave it alone for a few days, but if the leaf shows signs of getting infected or wilting, then I would pull it off and move on with my life.
