That's why the WTS discourages giving anything materially or time in helping non-jws.
Better to walk by some cold and unfed, and say "be warm and well fed" and you have fulfilled your Christian obligation.

In fact, even though pity for the people prompted Jesus to care for them in a physical way, his chief interest was in offering them the spiritual help their religious leaders had failed to provide. (See Matthew, chapter 23.) Jesus was “the fine shepherd,” one willing to surrender “his soul in behalf of the sheep.” (John 10:11) Because he gave this preaching activity—not engaging in social work or building hospitals or running relief agencies—top priority in life, he was later able to tell Pilate: “For this I have been born, and for this I have come into the world, that I should bear witness to the truth.”—John 18:37.

The Gospel accounts relate that Jesus Christ regularly performed good deeds for those who were poor or who had other needs. (Matthew 14:14-21) To what activity, though, did he give priority? On one occasion, after having spent some time helping those in need, Jesus told his disciples: “Let us go somewhere else, into the village towns nearby, that I may preach there also.” Why did Jesus interrupt his work in behalf of the sick and needy in order to resume his preaching activity? He explained by saying: “It is for this purpose [that is, to preach] I have gone out.” (Mark 1:38, 39; Luke 4:43) Although doing good deeds for people in need was important to Jesus, preaching about God’s Kingdom was his primary mission.—Mark 1:14.
Real-life experiences from around the world demonstrate that when people understand and follow the Bible’s practical counsel, they are better equipped to deal with the daily problems of life, including poverty. Moreover, the Bible’s message of God’s Kingdom that is preached by Jehovah’s Witnesses today gives people a hope for the future—a hope that makes life worth living, even under the most trying circumstances. (1 Timothy 4:8)

Would it violate any Christian principles to contribute to a United Givers Fund campaign conducted annually at one’s place of employment?—M. P., United States.
Whether a dedicated Christian will contribute to such charitable drives or not is something for each one to decide for himself. He may justly feel that he is already using all his available resources in a charitable work, that of preaching the good news of God’s kingdom, and that therefore he is not under obligation to contribute to other forms of charity. He also might well reason that his money will do more good if spent in some other way, in view of the large overhead that certain charitable organizations have, the officers of some receiving extremely high salaries. So it would be a burden of responsibility that each Christian would have to bear himself as to what would be the best thing for him to do under the circumstances.—Gal. 6:5.
