I have talked before to apostates; some have come back, and some have not. I don't kid myself that I have anything to do with people's individual end-of-the-day choices. Guidance is, as brother Hufaizah, said from Allah. We do not guide anyone; we can encourage them and support them and advise them.
1. Some just want to experience a different side of life because they felt pigeonholed by Islam.
2. Some had bad experiences of what religion is within their own homes with religion being forced down their throats and everything was ritualistic.
3. Some just leave because of emotional reasons which can include anything from having had a loved one die or just lack of support from Muslim community if they were converts.
4. Some have questions regarding specific things that were either ignored or not answered in a way that satisfied their hearts.
5. Some never learned Islam and didn't have a relationship with Islam with which to begin.
The people who fall in the above five categories are people you should definitely you can expect with to have rational conversations and have them return to Islam when they deal with their issues at some point in life or if they meet with people who can show them the face of true Islam which is a mercy to humanity.
On the other hand, I would note that there are some persons in the category who become, after leaving, quite obsessed with Islam, which is frankly on an individual level even quite unhealthy, and their entire existence seems to revolve around Islam more after leaving than even when they were Muslim; of these, some use vitriol creating deliberately hatred for Islam and Muslims to the point where it is actually quite scary, attacking anything Islamic to the point wherein I've seen even read non-Muslims becoming uncomfortable with what is being said. To be honest, these kinds of persons are dangerous because they are quite irrational, and I would call them extremists in their own right, and I would advise people to stay away from these kind of people because they are what I would call "toxic" personalities. In fact, a good article regarding them would be "
Toxic People: 12 Things They Do and How to Deal with Them." And I'm going to go out on a limb and say that anyone who befriends them in real life will find that these people appear to be saying to the truth in interests of everyone but if you seek deeper will find that they're no friends of anyone but their own selves. Then, in that case, best is to go on about your own life; you are free to make supplications to God for them to find guidance, but it's best you leave them alone otherwise, because toxic people are generally not good for anybody, not even themselves in the long-run.
Obviously, this is a generalized post and doesn't cover all possible categories; it is post meant to help you know and decide for yourself what you should do in regards to a specific person.

I want someone to let me know. Should we really view them as sub-humans? Should we really be harsh with them? Can't we be friendly?
Cuz I feel we are just being the cause for their resentment if we fuel the fire..... and then helping shaytaan.
And Allah :swt: knows best.
