Ohhhhh no you don't, I'm not falling for THAT trap. Sure, there's a nice little easy-looking bunny I can kill...what's beyond that? One ten times its size with fifty million HP, an immunity to physical attacks, and the ability to one-shot my party in one fell swoop by shooting unblockable lasers from its eyes? Noooooo thank you.
If there is an easy route around it, you're probably meant to take that route, and if you don't the game will knock you on your backside for ignoring it. If I was going to try it, I'd save the game first, then I would proceed VERY carefully after that, saving every few seconds, waiting to pay the price for my wanton act of needless slaughter. Nobody ever puts an easy kill in the middle of the road with another available route unless you're supposed to ignore it. It's blatant setup bait. No chance.
