We aren’t talking about “we” were talking about you. Lions in general may be at the top of the food chain but an individual disabled lion isn’t and is liable to get taken down by a species “lower down” like hyenas.

If you’re justifying eating meat by the ability to kill another animal then unless you can prove you can kill a cow you shouldn’t be eating steak.

You aren’t a predator at the top of the food chain, at best you’re a kleptoparasite appropriating the kills of others using money.
