Lyric discussion by Gabriel88 

The line is kill us faster not kill our past time.

the song is about a guy that likes his girl more than she like him. Kill us faster just to find your heart means that he'll deliberately try and end their relationship to see if she'll try and hold on to it, to see if she really cares

The fall asleep line means that if she doesnt try to hold on then he'll stop trying and he will let them break up (wake up when you're gone).

The title is an proclaimation to her beauty. An Amethyst is a purple stone. It's really pretty and that is what he is calling her.

The body line is about how he needs to admit to himself the problems in his relationship or learn to not care about them anymore

the line about the eyes is about how he pretended to be someone she would care about but she didnt care anyway
