I would start with assumption that strangling, cutting or beating someone is likely to be illegal. There are not that many countries with bdsm exception to those. And strangling is literally the most dangerous of all those. If you are strangling someome under assumptiom that of course it must be legal, you are likely breaking the law in all kinds of unaware and dangerous ways. And yes, in domestic violence situation, strangling is pretty consistent predictor of actual murder attempt later on.
