A very reasonable thing to do … but what point are you trying to make? *“Mercy does not destroy justice …”. *OK, how should that comment be applied? Are you arguing that capital punishment should be avoided in all cases as acts of mercy? It would be helpful if you would make your point and then support it with a relevant citation instead of simply quoting Aquinas and leaving it to me to figure out how you meant it to apply.

That citation of Aquinas ties to my entire argument throughout this thread. However, since you need things broken down to minute detail, I will do so. My comments in red.
God acts mercifully, not indeed by going against His justice, but by doing something more than justice (this does not mean just punishment and something else besides. Indeed, it can mean something more complete than, yet different from the just punishment); thus a man who pays another two hundred pieces of money, though owing him only one hundred, does nothing against justice, but acts liberally or mercifully. The case is the same with one who pardons an offence committed against him, for in remitting it he may be said to bestow a gift. Hence the Apostle calls remission a forgiving: “Forgive one another, as Christ has forgiven you” (Ephesians 4:32) (note: the forgiveness mentioned here does not preclude all punishment. Yet, if there is forgiveness, then mercy is possible). Hence it is clear that mercy does not destroy justice, but in a sense is the fulness thereof (applying this to the current topic: the small mercy of commuting a death sentence to life imprisonment is a more perfect application of justice than mere execution). And thus it is said: “Mercy exalteth itself above judgment” (James 2:13).

Certain works are attributed to justice, and certain others to mercy, because in some justice appears more forcibly and in others mercy. Even in the damnation of the reprobate mercy is seen, which, though it does not totally remit, yet somewhat alleviates, in punishing short of what is deserved (“punishing short” i.e. by withholding the full force of punishment due for the crime. In the case of a murderer, by not executing him when it is possible to remove him from society without his death).
In the justification of the ungodly, justice is seen, when God remits sins on account of love, though He Himself has mercifully infused that love. So we read of Magdalen: “Many sins are forgiven her, because she hath loved much” (Luke 7:47).
