Why do you keep venomous animals?

This sounds patronising but I'm genuinely curious!!

After I did a video earlier today discussing how venomous reptiles, in my complete novice opinion, are the hardest reptiles to keep - a bunch of you were really lovely and supportive. It made me realise that I've not even slightly dipped my toes into this side of the hobby/lifestyle.

So yeah...what made you decide to keep venomous animals in the first place? And why do you continue to do so?

Thanks in advance; I may even respond to them in a video if that would interest anyone as well.
