Why do I think like this?

see your doctor your suffering from depression.

Probably because you're human, and have been through a hard time.

To be honest, unless you have always had these feelings, then i'd put it down to stress and anxiety caused by recent events. However, it is never a bad thing to talk to your GP about such feelings. It may seem hard to talk about and like it's not right, but you'd be surprised how many people have these sorts of thoughts.

I can almost relate, and have had these thoughts before, more when driving a car than holding a knife. Knowing the fragility of human life and the power you have to change it can be a truly terrifying concept.

If this is something which dominates your life, then seek help. Counsellors are incredible and very good at what they do, and they will not judge you for anything you say/think/feel.

I have seen a counsellor in the past, and have had similar thoughts. I also have a degree in Psychology, so kind of know what i'm talking about. But the best advice i can offer is to just relax and focus on positive things. Like it says down the side of my body in Latin - 'Don't worry, be happy'

Its just a phobia, like being scared of heights. I'm fine in an aeroplane but i cannot get onto a balcony as I'm always afraid I'll have the urge to jump off, it's crazy because I would never jump off but I never take the chance. Unless you are hearing voices in your head etc you should just train yourself to deal with the anxiety and hopefully you will be fine, or maybe get hypnotherapy.

No your not insane, some other people have random thoughts similar to these. Not all the time like you not being able to pick up a knife without worrying like that but similar. Visit Purgethepurge.com it might help you. Hope I helped!
