My friend's argument about him was that Buddha came from a non-Christian/Jewish area and that he was someone who developed philosophy for the suffering.
I normally can't agree with my friend's words because it seems unlikely that a person claiming to reincarnate and return to this world on his own was good.
My friend claims she's still Christian. Is it still possible that she is while believing Buddha was good?

Warning Against Antichrists
18Dear children, this is the last hour; and as you have heard that the antichrist is coming, even now many antichrists have come. This is how we know it is the last hour. 19They went out from us, but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their going showed that none of them belonged to us.
20But you have an anointing from the Holy One, and all of you know the truth.[
d] 21I do not write to you because you do not know the truth, but because you do know it and because no lie comes from the truth. 22Who is the liar? It is the man who denies that Jesus is the Christ. Such a man is the antichrist—he denies the Father and the Son. 23No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.
24See that what you have heard from the beginning remains in you. If it does, you also will remain in the Son and in the Father. 25And this is what he promised us—even eternal life. 26I am writing these things to you about those who are trying to lead you astray. 27As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him.
Colossians 2:8
See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the basic principles of this world rather than on Christ.
James 3:13-18
Two Kinds of Wisdom
13Who is wise and understanding among you? Let him show it by his good life, by deeds done in the humility that comes from wisdom. 14But if you harbor bitter envy and selfish ambition in your hearts, do not boast about it or deny the truth. 15Such "wisdom" does not come down from heaven but is earthly, unspiritual, of the devil. 16For where you have envy and selfish ambition, there you find disorder and every evil practice.
17But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere. 18Peacemakers who sow in peace raise a harvest of righteousness.
