I don't think any of us has a "good reason" for keeping snakes. The answer is because we want to. My cousin once asked me why I had two dogs, "why wasn't one enough for you?"...well, because I wanted 2, but my response was "why did you have 3 kids, why wasn't one enough for you?"
To the OP, I think you should work towards goals, but in a safe and responsible way. The issue here is that I wanted snakes, but the worst that's going to happen is I'm going to take a bite that I can put a band aid on; the worst that will happen if you take a bite is death. Decisions with bigger consequences deserve to be taken more seriously.
