How on earth can someone who claims familiarity with Aquinas be so oblivious to the concept of PERSONAL RESPONSIBLITY FOR ONE'S OWN ACTIONS?
I'm familiar with the concept. Yet we are our brother's keeper. The purpose of society is to promote the common good. Turning a blind eye to vice is not charitable, it's evil. Specifically, it's a sin of omission.
Genesis 42 Later she gave birth to his brother Abel. Now Abel kept flocks, and Cain worked the soil.
3 In the course of time Cain brought some of the fruits of the soil as an offering to the LORD .
4 But Abel brought fat portions from some of the firstborn of his flock. The LORD looked with favor on Abel and his offering,
5 but on Cain and his offering he did not look with favor. So Cain was very angry, and his face was downcast.
6 Then the LORD said to Cain, "Why are you angry? Why is your face downcast?
7 If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must master it."
8 Now Cain said to his brother Abel, "Let's go out to the field." [4] And while they were in the field, Cain attacked his brother Abel and killed him.
9 Then the LORD said to Cain, "Where is your brother Abel?" "I don't know," he replied. "Am I my brother's keeper?"Luke 10
30 In reply Jesus said: "A man was going down from Jerusalem to Jericho, when he fell into the hands of robbers. They stripped him of his clothes, beat him and went away, leaving him half dead.
31 A priest happened to be going down the same road, and when he saw the man, he passed by on the other side.
32 So too, a Levite, when he came to the place and saw him, passed by on the other side.
33 But a Samaritan, as he traveled, came where the man was; and when he saw him, he took pity on him.
34 He went to him and bandaged his wounds, pouring on oil and wine. Then he put the man on his own donkey, took him to an inn and took care of him.
35 The next day he took out two silver coins[5] and gave them to the innkeeper. 'Look after him,' he said, 'and when I return, I will reimburse you for any extra expense you may have.'
36 "Which of these three do you think was a neighbor to the man who fell into the hands of robbers?"
37 The expert in the law replied, "The one who had mercy on him." Jesus told him, "Go and do likewise."
