Indeed they are.
The cherry picked list of orders to burn and destroy are not representative of his entire demeanour towards civilian populations, which was commented on readily by most observers during his lifetime. Note the constant reference to hang those in arms, the hanging of unreliable translators and spies was unfortunately part and parcel with the business of war in India. The burning of villages was uncommon under Wellington’s command, and I believe this particular instance is specifically due to the difficulty's presented by hunting down the rebel Doondiah Waugh, hence the harsh treatment to those who had given his marauders support, make no mistake Doondiah committed far greater atrocities in his brief reign of terror in Mysore country.
We may also observe the clear orders given by General Wellesley upon the commencement of the Pune and 2nd Maratha campaign that forbid burning and looting, I believe it was punishable by death.
Overall when seen within the proper context, the view presented within the quotation marks proves (to those that know) little but that commanding officers are forced to act ruthlessly in the pursuance of their duty. It is regrettable that the list has already been swallowed by some and carried away to portray Wellington as a monster.

Josh.

This letter from Wellesley dated 26th May 1800 helps set in context his mission in the campaign against Dhundia Waugh:

‘I have information that letters have been received by most of them, either from him, or from others written in his name, calling upon them to take the opportunity to rebel against the Company's government, or that of their allies; and his invasion of our territory is looked to as a circumstance favorable to their views. The destruction of this man, therefore, is absolutely necessary for our tranquillity.’
