Exactly. Jesus was quite harsh with the arrogant legalists of his day who accused HIM of being unloving / unrighteous.
Like the DIShonest seekers of today, they found fault WITH HIM for saying that he has the right to have mercy on whom he wills, and the right to harden whom he wills. That he, the potter, has power over the clay .. to make one for honor and one for dishonor, if he wants to. That so what if he wants to show his wrath and make his power known, endured with much longsuffering the vessels of wrath prepared for destruction ... so that he might make known the riches of his glory on the vessels of mercy which he prepared beforehand for glory". [Romans 9:14-23] (See #118)
It reeeeeeally sends some sinners into raging anger that even though God says ALL fallen sinners deserve death, not all will get what they deserve.
