No it didn't. Allocating 60% of the entire country's agrarian budget and feeding 3 million mouths per day for 2 years straight and ignoring the European famine's deaths in England, Wales and Scotland to feed Ireland is not what we call 'Let em Starve'. Despite popular misconceptualization of the famine, Britain, even the idiotic Whigs when they took power, did try to mitigate the famine, but in less than stellar ways. Another major problem the british found was that the millions of tons of grain they were sending to ireland were rotting in the docks and were being stolen by poor Highlander and Irish sailors in the transport duration between the celtic channel.This. IOTL the British government was basically like 'Irish Catholics? Nah let 'em starve'. I mean, they didn't do nothing but what they did do was ineffective af, especially once the public works projects got rolling. Those actually CONTRIBUTED to the death toll rather than mitigated it.
Anyways to go to the OP, have Peel stay. His program was successfully feeding 3 million irishmen and the numbers were rising approximately 1000 to 2000 per day and would have mitigated a lot of deaths. Prevent Russel's folly and the deaths of the Irish famine would have looked similar to the scottish, welsh and english tallies of the greater european famine of the time.
