No, no. You can do it. Not counting sub/MPCT costs, I’ve been isk positive on different characters doing different forms of PvP (i.e. ganking, sov warfare, structure bashing). Moreover, I understand how the grind can be a downward spiral (grind → reinvest to increase efficiency → grind more to recoup investment → reinvest/invest → grind even more).
The idea that you need to grind in order to buy ships for fun is a myth. If you don’t want to grind anymore, then don’t. Of course, biomassing a toon is a bit extreme. But if that’s what you have to do in order to walk away from the endless grind, then I say go for it.
Do whatever it is that you find fun/rewarding.
