The crucible... Act 1- what other issues seem to be undercurrents to the witchcraft concerns?

1) Betty's illness

2) Adultery (John and Abigail)

3) Parris' concern with reputation and status

4) Putnam's desire for revenge (and the fact that he will not only wreak vengeance but profit from the deaths of others)

5) hysteria (mob mentality)
