It looks as if its suffering from lack of sunlight and being in that pot. The trunk is mighty thin for its height and the internodal spacing looks mighty stretched, even for a seedling. I would cut it back, put in a larger pot or in the ground and make sure it gets as much sun as possible.
If you have the room and patience, growing it to fruiting is not a bad thing. I have tasted many a great seedling fruit just as i have tasted many a garbage seedling fruit. Hey, if you let it grow till fruiting and the fruit is not hood, you can always top work it at that point.
