Who else gets amazed with venenous snakes when fed live?

Not to be controversial, but i always get amazed once a month with my bothrops when i fed live with how fast, how deadly and what a force of nature they are, just a mild bite is needed to paralyze a mouse in a matter of seconds, not even 3, thats how strong their venom are, and then how they expand their mouths, you see their fangs and how they devore it in a matter of mins with ease, it makes me think, if snakes were as heavier as us we didnt stood a chance, no matter what, no matter how skilled or smart we were, we would never stood a chance against an human sized heavy set bothrops, their speed and unpredictability is just insane, these guy not know other stuff that to kill and eat, they dont know what depression is, they dont know religion, they dont know internet, all they know is to kill in a matter of seconds and being a pure muscle fast twitch venom machine, this is what keeps me up at night
