I don't think snakes would ever hae anything personal against someone, but I do believe that they have some emotion. My first BP, Candice, seems like she does have feelings. Like, when I take her out, it seems like she's almost excited to be out and be handled (she always loves to be handled). She also likes it when I pet her head, strangely. She seems to do things that snakes don't like to do. She isn't a scardy cat BP, like my other BP. When she gets startled, she'll move her head back a little then puts it forward again. Here's a strange story I heard one time, and it is true:

One day this lady had to take her Burmese python to the vet while her husband was at work. The snake just needed it's regular check ups to make sure that the snake is healthy. Before she went to the vet, she needed to get gas for her car because it was on low. She put the large python in the back seat of her car, and the python curled up in the back seat and stayed there. The lady got out of her car to get gas, and when she finished she got right back into her car. As soon as she got into the car, a man with a knife got in the front passenger seat and told her to drive while holding the knife up like he was going to stab her if she disobeyed. The snake in the back seat struck out and bit down on the man's shoulder. Then, the snake made an attempt to wrap around the man. The snake stayed like this, wrapped around the man, when his owner called the police. The police quickly came over, and with some coaxing from his owner, the snake let go of the man. This story was in a newspaper arcticle.
