Golden Eyes felt that after he joined the Double Rest Sect, his heart had indeed softened a bit. He didn't mind that Wendy and the others had wanted to kill him previously.
A group of starving kids wanted to learn to rob to fill their stomachs, which in Golden Eyes' view, was nothing serious at all.
The bad things he had done before were much worse than this, and if one day he truly died at someone's hand, Golden Eyes felt he probably wouldn't have any regrets.
The reason he lamented his softened heart was because previously, his eyes only focused on the mission and never attended to anything beyond his tasks.
But this time, breaking precedent, he agreed to give Wendy and the others a lift, even if it was only after the mission was complete, which was quite an unusual thing for him to do.
However, Golden Eyes didn't think too much of it. After sleeping and restoring some of his energy, he headed out early the next morning to check the marks he had left the previous day.
