St Thomas’ assertion is true when understood to be a reference to the first font of morality - that is, the “intended end”. So yes, a man acquiring a gun holding the view that anyone setting foot in his house will be shot dead, is contemplating a gravely wrong act. For we may not intend as an end harm to another. But, in the course of self-defence, we may judge that to save ourselves (intended end, good moral object) requires an act to end the life of the aggressor (intended means, physical evil). The physical evil of that death may be licitly intended as a means to the end of self-defence.We know that unusual and extreme circumstances make situations where double effect principle might apply, theologically difficult. Take for example US gun policy. The unanimous feeling of most Western countries is that owning a gun with the express purpose of killing or threatening to kill an aggressor based on personal interpretation at any given time… is outside the bounds of blameless self defense.
“But as it is unlawful to take a man’s life, except for the public authority acting for the common good, as stated above (Article 3), **it is not lawful for a man to intend killing a man in self-defense, **except for such as have public authority, who while intending to kill a man in self-defense, refer this to the public good, as in the case of a soldier fighting against the foe, and in the minister of the judge struggling with robbers, although even these sin if they be moved by private animosity.” - Summa theologica
The US believes that this intention to kill infused in the actual ownership of a lethal self defense weapon, does not equal ‘intending to kill a man in self-defense’. In other countries, that is exactly what it equals. The Church hasn’t directly commented on the intentionality of the US self defense gun as yet but the fact is that many, many other Christian countries have rejected such a policy according to conscience. It is always going to be influenced by a myriad of unique circumstances at the end of the day. The nuns from the Congo demonstrate such circumstances.
Thus, a person does not - IMHO - necessarily intend wrong acts by acquiring a gun for self-defence. Nevertheless, the act may well be rash and potentially cavalier, and find the notion of every house equipped with a gun as quite frightening.
