For 'capable' Malone read 'incapable.' Perhaps the right word would be culpable, and it and 'frail' should be transposed, as 'frailty' follows.
"A man that more detests, more stirs against."
For 'stirs' I read strives, as Shakespeare nowhere uses 'stirs' in conjunction with 'against.'
"And in my presence,
They are too thin and base to hide offences."
For 'base' Malone read bare, which may be right.
