it all stands on what's important to you and how much your willing to fight for it. example: i care about my dog, friends, and family. I would do absolutely anything for my dog, even turn down a million dallars, but the extent is probably killing myself or losing a limb. my family, i love those who are left, but i would only go as far as loaning money or helping them move. my friends, well it varies. if the person has been good to me i'll do as much as i can, if they are assholes i probably wont help much. I dont HAVE to fucking help ANYONE. its a choice. its all choices in the end. do or dont. everyone has different reasons for why they do things.
my personal opinion on why people get jobs is because thats what they are brought up to do or they just are so used to a steady income they dont feel comfortable to adapt to any other kind of life style. they like to pay rent because they get a heater and air conditioner, a tv, a shower, and a safe place to sleep and put their crap. they dont have to pay rent. they just dont want to spoon with people like me under a bridge haha and in a case like with kids, you dont have to do anything to keep your kid, but you give a flying fuck so you do your best. you care about your kid so you fight to keep them and care for them.
i could kill a person right now, but i wont. not because of fear of jail time, i just think it would be messy and stupid. no matter how many you kill they just keep comming. i choose not to because i weigh out the results and mix that with my judgement then think "yeah its probably not worth it." now if someone killed my dog, well damn it i'm going to kill them. in my eyes a dog deserves to live more than any human. everyones different though. there is no right and wrong in the end. just choices.
