Keeping venomous snakes, when done responsibly, is not any more "crazy" than keeping any other animal. That being said....hot snakes are not for everyone and there are people out there who have them and shouldn't.
About the topic of venomoids.....this is an extremely controversial topic in the herp hobby, for good reasons. The vast majority of venomoids are created illegally, inhumanely and irresponsibly. I myself am vehemently opposed to hacking up a venomous snake simply because a person wants a "de-venomized" cobra to show off to their friends. Honestly....I could write a 10 page essay on this topic and still have more to talk about lol.
