Keeping a pet lion vs a pet venomous snake is like comparing oranges to apples. One is a 600+ lb of muscle and teeth, some owners allow them to roam free around the house or live with the household members, less predictable and can react aggressively without being provoked. The other usually bites out of fear, more predictable for an experienced hot keeper who knows what to look for, and can't break through a secured locked enclosure.
I don't keep hots and have no plan to, mostly because I'm not a fan of display pets in general. I think they are beautiful animals and most keepers who gets licensed to keep them earned their stripes to do so. On the contrary, in most states you can pick up a lion cub with little to no experience.
