Think you that GOD doesn't love those who are condemned to hell?

Why would anyone imagine GOD would cease to BE GOD for any reason at all?

GOD IS LOVE. HE would no more stop LOVING than HE would stop BEING.

Why then, are people condemned to hell, IF GOD loves them so much, WHY doesn't HE find some other way to get rid of sin?

First of all, the people who are condemned to hell, DON'T WANT to get rid of their sins.
That's why they are there. They haven't repented from sin and asked GOD to forgive and cleanse them.
Some people who are in hell, asked for forgiveness, but they wanted nothing of the cleansing. They chose to live their lives however they pleased. Not caring what GOD wishes at all.
The BIBLE is here for all who will to learn of GOD and HIS WAYS, DESIRES, and REQUIREMENTS.
GOD is never made a fool of. The BIBLE says, what ever a man plants, that's exactly what he is going to harvest. IF a man plants sins he will harvest death and hell, if a man plants works of righteousness BY THE POWER OF THE HOLY SPIRIT he will reap everlasting life.
THIS IS NO "WORKS SALVATION!"
 By GRACE you are saved through FAITH.
Before a man is "SAVED" there is no way on earth he could ever work any works of righteousness. Sin is master and lord over the unsaved. There is no choice. He is a SLAVE to sin.
AFTER one accepts CHRIST into his life, HE is become a NEW CREATION all things are passed away, behold ALL THINGS are become NEW.
And it is no longer the man who is alive, but JESUS LIVES inside him.

Now, there is a choice! The man is ABLE to say NO to sin and yes to CHRIST.
Horrible, Ungrateful, Wretch of a man (or woman) who would choose to go on in sin, after THE GREAT COST OF THE LORD GOD ALMIGHTY to liberate them from sin. - And yet, FATHER GOD STILL LOVES THEM
These are the people to whom JESUS says:
And why call ye me, Lord, Lord, and do not the things which I say?
and again JESUS says:
Matthew 7:21  Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22  Many will say to me in that day, Lord, Lord, have we not prophesied in thy name and in thy name have cast out devils? and in thy name done many wonderful works?
23  And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Now, if preachers will be send away from HIS presence, how much more anyone else?
Is JESUS inside you?
Are you letting JESUS do the living, the HOLY SANCTIFIED UNTO GOD LIVING,
picking up your cross daily and following JESUS, by FAITH and the POWER of The HOLY SPIRIT putting to death the works and desires of the flesh OBEYING JESUS in loving your neighbors as HE first loved you?
(how did JESUS love you? HE left HIS comfortable home and came searching for all the lost to save them from their sins, to DIE to SAVE them - yes, and that is EXACTLY how we must live!)
 OR
 are you living the 'carnal' life.  Living by what you see, feel, taste, and smell? Living to the flesh?
2Co 13:5  Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
