Abetadad but even through contemporary eyes, the Penal Laws of the 17th and 18th century Ireland were viewed as harsh. It's not only retrospective judgement.
To view the circumstances of the Famine as an event of the Victorian era is simplistic, and is to overlook the prior 200+ years of systematic disenfranchisement that created the scale of the disaster. The legal framework imposed by Britain on Ireland created monoculture subsistence farming at a level of scale and poverty that was not present in Britain. The almost total reliance on a single crop was the end result of a population driven to desperate poverty by disenfranchisement and exploitation, the root of which lies in the Cromwellian clearances and the Penal Laws.
The Great Famine in Ireland simply cannot be aligned with local famine conditions in England because the socioeconomic and ideological backgrounds were entirely different, as was the severity and the response to provide relief.
Ireland was not alone in its awful treatment under British (English) rule. The highland clearances in Scotland following the Jacobite rebellion were a similar deliberate disenfranchisement and suppression of Catholic populations. The potato blight of the 1840s also caused many deaths from famine in highland areas already driven into poverty. However, the scale and severity does not come close to equalling that of Ireland.
It sucked to be poor anywhere in the 19th century, but it wasn't governmental ineptitude or mismanagement that made the potato blight so lethal in Ireland. It was years of deliberate policies to remove all political and social power from Catholics that left the Irish population extremely poor and vulnerable. The blight was the tipping point.
