Taking someone to purchase drugs

Q: I have a Muslim worker who is addicted to mandrax. Daily after work he must smoke. Sometimes he works late and the place where he needs to buy the tablets (drugs) is not safe so he asks me to take him there so that he can go in and buy it and I must drop him home. If I don’t take him, he will walk down and it’s not safe. I have been doing that but it’s bothering my mind, am I not a party to the sin? What should I do? Even though by my not taking him he won’t stop. 

Deleting a recording of an incorrect statement one made

Q: If someone did a radio play for university coursework and their character in the script said an utterance of shirk, for example if they said "christ" and they recorded this, does that mean the sin is there and even if I deleted the recordings but there might be a file somewhere.

I knew it was wrong but I thought because its a character and I'm speaking the lines of that so it doesn't matter too much. Then I remembered how bad it was and the fact that it was part of the radio play. Now I'm trying to delete the recordings and finding out if it's anywhere else on my laptop. I deleted them and edited it out of the radio play but I am still stressed. Its because its recorded and I feel like if the cache or bit of the recording is still in the computer somewhere then is it still shirk?

What should one do with an Easter egg that was given as a gift?

Q: I have a question about easter eggs. I know it's obviously haram to sell and buy them. But today a neighbour has left in front of the door of my hause an easter chocolate egg, although she well knows that my mom and I are Muslim since 3 years, alHamdulillah.

Now I don't know what to do with this chocolate egg. I think it's also haram to eat easter eggs as it's haram to buy them. So what should I do? Do I have to throw away the egg (naturally destroying it so nobody can eat it) or can I break the chocolate into many pieces to consume it during the year as "normal" chocolate?

Father cursing his son

Q: If a father says to his son "if it's true that you committed what I suspect you, May Allah curse you" and surely the son committed what his father suspected him (Though the father has confidence his son will never do that due to his (son's) good character). Now:

1. What is the ruling on that curse?

2. Is the son still a Muslim?

3. Can the son, despite being cursed pave his way to paradise?

4. If surely Allah cursed a person, he distanced him from his mercy, how could that son draw nearer to Allah's mercy.

5. The father is quite happy with the son as I write this, because he obeys whatever he asks him to do, not knowing the son is cursed by him. What is your advice to the son?

Superstitious beliefs

Q: Please expand on the subject of superstitious beliefs in Islam. E.g. whistling in the house or cutting paper and rocking. Apart from the many other common household beliefs that are becoming a daily problem.
