Well by the time he executed Bishop Fisher and Thomas More, he wanted to be āmore Catholic than the Popeā. He wanted to keep all the Catholic things he liked, but he wanted to be the Head of the Church. Power-hungry, midlife crisis, symptoms of syphilis, the āmale successionā, warped sexual views, egotism, combined with a utilitarian philosophy quick to āuseā the rebellious issues in Protestantism while coyly remaining āon the fenceā so that he appeared to support both the Protestants and Catholics. . .
Not to mention that with the dissolution of the monasteries and distribution of the wealth to mainly (but not solely) Protestant lords, there was a vested interest for them to maintain the status quo and de facto shift to being a Protestant country. Even the Catholic lords who had benefitted from the influx of wealth were unwilling to give that up.
And in the end, what happened?
The son who was so important was a child ruler who died as a teen. The legitimate female heir Mary had her youth destroyed, her chances for a ānormalā marriage destroyed, suffered survivor guilt after her motherās death. . .and wound up dying childless.
The middle child whose mother was executed for adultery, herself banished from the court as a young girl, investigated for unseemly sexual conduct with her uncle by marriage who had married Henryās last wife on Henryās death (never proven), sent to the Tower by her sister, became queen. . .never married but spent years, into her 50s, playing herself as a pawn on the marriage market, tried to āstraddle the fenceā religiously like her father but wound up signing the papers approving the execution of her own cousin Mary Queen of Scots who had been held as a prisoner by Elizabeth for nearly 20 years while kangaroo courts played with concocted evidence and Walsingham and Cecil stacked the country even further to keep their titles and wealth. . .
One canāt help but feel sorry for Henry. As with so many, he wound up committing atrocities to achieve āwhat he wantedā because he convinced himself that what HE wanted had to be what GOD wanted.
