Loans actually can be very risky, but if you know that you are able to pay it back then it should be no problem at all.
Take only a loan when you need something that is important and if you can pay it back.
If you loan some money of course it is your responsibility to pay it back once you gave the exact date then pay it on the exact time you gave because people are trusting you because you ask a permission to barrow some money and if you can't pay that back then don't make some loan
Yes and it is very hard to realise who is going to pay back and who doesnt so its hard thing to check.
Thats why loans are risky too cause its impossible to know if the person at the other side is going to keep their deal or not so it could turn into a bad scam.
