"And if the vibe was suicide Then you would push da button But if ya bowin' down Then let me do the cuttin'"

I think that what he is saying here is that if everyone else was committing suicide, then you (the general public) would follow them and "push da button". I feel that in the last two lines Zach is saying how he is not going to follow the crowd just for the sake of following the crowd, "then let me do the cuttin'" - he's saying that he'll do it whether or not other people are doing it or approve of it.
