Given where he was, McDonnell was correct.
Churchill was pretty hardline and was effectively in the wilderness until ww2, when we needed a hardline leader to get us through. That doesn't excuse previous "sins"
Certainly on balance he did more good than harm but sending in troops to police an action was churchilll's first reaction and his attitude to India was scandalous
A previous sin.......... "Churchill's most important indirect role in these reforms was his assistance in passing the
People's Budget and the
Parliament Act of 1911.
[4]:157–166 The Budget included the introduction of new taxes on the wealthy to fund new social welfare programmes. Churchill biographer
William Manchester called the People's Budget "a revolutionary concept" because it was the first budget in British history with the expressed intent of redistributing wealth to the British public.
[24] When the Budget was discussed in 1909 he did feel some ambiguity over it.
[4]:159 But despite his doubts about its effectiveness, he launched himself into the fight for the budget and accepted the presidency of the Budget League, an organisation set up in response to the opposition's "Budget Protest League".

Sending in troops you say ..........."In 1910, coalminers in the
Rhondda Valley began what has come to be known as the
Tonypandy Riots. Initially, the chief constable of Glamorgan requested that troops be sent in to help police quell the rioting. Churchill, when he learned that they had been sent, allowed them to go as far as
Swindon and
Cardiff and authorised the commanding general to advance further if he should judge it necessary. Churchill, who had already forbidden the use of forces in another industrial dispute at
Newport, did not favour deployment of troops, fearing a repeat of the
1887 Bloody Sunday in
Trafalgar Square. In particular, Churchill forbade the use of troops as strike breakers.
[6]:48 On 9 November, the
Times leader criticised this decision, saying that responsibility for the "renewed rioting late last night...will lie with the Home Secretary [Churchill]" for countermanding the chief constable's request for troops. In spite of this, the rumour persisted that Churchill had ordered troops to attack, and Churchill's reputation in Wales and in Labour circles never recovered.
