Why is it that all the wild life I get to see is either dead or about to be?

The other day I was sitting around my house as usual when all the sudden we hear this chicken squawk, which is an all too frequent occurance, but this one´s diffrent somehow, more desperate, more like a last squawk. One of my host sisters gets up to go investigate, the sound coming from one of the overgrown gardens. Suddenly she´s screaming " Kuriju! Kuriju!" and everbody come running. My moms grabs a bamboo pole and we get the garden and I see a boa constrictor wrapped around a now dead chicken. Mom starts wacking it with the bamboo untill big sister arrives with the hoe and beat the poor thing to snake heaven. Biggest snake I´ve seen out in the wild, probably about 5 feet long and as thick as a mans forearm. I wish I´d gotten to see it eat the chicken rather than get is head flattened... repeatedly. They really don´t like snakes.
