Yes we dont owe them what we achieve. But I think if you know to yourself that you're somehow capable to lend, especially if this particular person is close to you (a family member) then if its me I dont see any problem with that.

Though its really satisfying to earn money through our own capital and hardwork. Because it doesnt necessarily mean that we need huge capital as a beginner, any amount will do, what matter is what you learn through that experience. Money is not hard to earn if you are hardworker and striving to get it.
