Just imagine what it will be like to find you still hate peanut butter, and then find the jar a year later with one knife-ful taken out of it, going mouldy in the cupboard, and then have to scrape the mouldy gunk out of the jar and wash the jar up with all those bits of gunky horribleness floating in the water.

If you are one of these despicable people who throws out glass jars into landfill instead of recycling them if they have even mildly unpleasant things in, do not tell me. Let me keep my illusion of respect.
